The advantage of $\\mathsf{PCA}$s is that they are able to overcome limitations of $\\mathsf{PCP}$s. A \\emph{succinct} $\\mathsf{PCA}$ has proof length that is polynomial in the witness length (and is independent of the non-deterministic verification time). Such succinctness is impossible to achieve for $\\mathsf{PCP}$s, under standard complexity assumptions. Bronfman and Rothblum (ITCS 2022) constructed succinct $\\mathsf{PCA}$s that are publicly-verifiable and have constant query complexity. Their scheme works only for a subclass of NP of relations that can be verified by a small-depth circuit, while assuming the sub-exponential hardness of the learning with errors (LWE) problem.We construct $\\mathsf{PCA}$s for \\emph{all} NP under any one of the following assumptions: (1) \\emph{polynomial} hardness of LWE; (2) $O(1)$-$\\mathsf{LIN}$; or (3) Quadratic Residuosity (QR) and sub-exponential Decisional Diffie-Hellman (DDH). Our scheme is publicly-verifiable, adaptively sound, and has constant query complexity.One of the main ingredients in our $\\mathsf{PCA}$ scheme is a new $\\mathsf{RAM~Delegation}$ construction that satisfies several desirable properties that may be of independent interest. Our $\\mathsf{RAM~Delegation}$ scheme supports RAM programs that perform both read and write operations, and it has a strong soundness guarantee. Previous constructions only supported a subset of these properties. Our scheme has an additional prover efficiency property. The space complexity of the honest prover is only proportional to the number of locations the RAM program writes to (and not to its running-time). Our construction can be realized under the same set of assumptions as in the $\\mathsf{PCA}$ construction.</div><div class="event_time">11:00 &bull; EPF Lausanne</div>        </div>        <div class="day_content_item normal"><div class="event_location uni_la"><a class="external" href="https://www.epfl.ch">EPF Lausanne</a></div><div class="event_type"><a class="external" href="https://www.epfl.ch/labs/cmgr/cmgr/geometry-seminar">Geometry Seminar</a></div><br /><div class="event_speaker"> Thiziri Moulla (EPFL)</div><div class="event_title">On the minimal volume entropy of finitely presented groups <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />In this talk, I\'ll speak about the minimal volume entropy of finitely presented groups and I\'ll give some properties.

So far, an in-depth characterisation of such sequences has been carried out in the case where the surfaces considered are discs, both in regards to the curvature blow-up points and the limit surfaces that can arise. In order to study the topology of the limit leaves of sequences of properly embedded minimal discs, Bernstein and Tinaglia first introduced the concept of the simple lift property, since such limit leaves satisfy this property. They proved that an embedded surface $\\Sigma\\subset\\Omega$ with the simple lift property must have genus zero, if $\\Omega$ is an orientable three-manifold satisfying certain geometric conditions. During my PhD, I generalised this result by considering an arbitrary orientable three-manifold $\\Omega$ and proving that one is still able to restrict the topology of an arbitrary surface $\\Sigma\\subset\\Omega$ with the simple lift property. In this talk, I will present which topological results can be extended in the case of sequences of minimal surfaces of arbitrary finite genus.</div><div class="event_time">17:00 &bull; Université de Fribourg, 0.05 PER23</div>        </div>        <div class="day_content_item normal"><div class="event_location uni_be"><a class="external" href="https://www.unibe.ch">Universität Bern</a></div><div class="event_type"><a class="external" href="https://www.math.unibe.ch/research/talks/colloquium/index_eng.html">Mathematisches Kolloquium </a></div><br /><div class="event_speaker"> Charles Noguera (University of Siena)</div><div class="event_title">Characterizations of (identity free) first order logic as a maximally expressive language <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />In the 1960s, Per Lindström showed that first-order logic is maximal (in terms of expressive power) among its extensions satisfying certain combinations of model-theoretic properties. The best known of these combinations are: (i) Löwenheim-Skolem theorem + Compactness and (ii) Löwenheim-Skolem theorem + Recursively enumerable set of validities. Philosophically, these results have been interpreted as providing a case for first-order logic being the ``right" logic in contrast to higher-order, infinitary, or logics with generalized quantifiers, which can be argued to be more mathematical beasts. An implicit assumption of Lindström\'s work is that identity belongs in the base logic. The classical Lindström theorems clearly fail for first-order logic without identity since first-order logic with identity is a proper extension. In fact, there are continuum-many logics between the former and the latter satisfying the compactness and Löwenheim-Skolem properties, and with recursively enumerable sets of validities. After going through the motivation and the main history of the topic, in this talk we will present our recent result that aims at amending Lindström\'s two central theorems so that they apply in the identity-free context. Our proofs make heavy use of a property that is not available in the presence of identity, namely, an unrestricted upwards Löwenheim-Skolem theorem that applies even to finite models.</div><div class="event_time">17:15 &bull; Universität Bern, Sidlerstrasse 5, 3012 Bern, Lecture Room B6</div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Tuesday, April 30      </div>      <div class="day_content">        <div class="day_content_item normal"><div class="event_location uni_ge"><a class="external" href="https://unige.ch">Université de Genève</a></div><div class="event_type"><a class="external" href="https://www.unige.ch/math/annonces/groupes-geometrie">Groupes et Géométrie </a></div><br /><div class="event_speaker"> Livio Ferretti (UNIGE)</div><div class="event_title">Framed mapping class groups and the monodromy of positive braids <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />A framing on an orientable surface with boundary is given by a nowhere vanishing vector field (considered up to isotopy).

There are many different knots and to distinguish them one uses invariants, algebraic quantities that do not change under deformations. In the 1980’s new, so called, quantum invariants were discovered by Jones and son thereafter generalized. These invariants are of combinatorial nature and can be understood from a physical perspective as Wilson lines in quantum field theory, as shown by Witten. Inspired by string theory, Ooguri and Vafa stated in 1999 a conjecture that gave an enumerative geometric interpretation of knot invariants: the invariants arises as counts of certain geometric objects, 2-dimensional holomorphic curves that end on a 3-dimensional space, the conormal of a knot, in a 6-dimensional space associated to the ambient 3-dimensional space where the knot lives. The mathematical treatment of the curve count suggested by Ooguri-Vafa is not straightforward, because of so called wall-crossing phenomena the count jumps under deformation. In recent work with Shende we managed to relate the combinatorics of knot invariants to the wall crossings and thereby found the mechanism for the relation between knot invariants and enumerative geometry. The talk will describe this construction and demonstrate how it leads to a proof of the Ooguri-Vafa conjecture.</div><div class="event_time">16:15 &bull; Université de Genève, Conseil Général 7-9, Room 1-15</div>        </div>        <div class="day_content_item normal"><div class="event_location uni_zh"><a class="external" href="https://ethz.ch">ETH Z&uuml;rich</a></div><div class="event_type"><a class="external" href="https://math.ethz.ch/s/talks-in-financial-and-insurance-mathematics">Talks in Financial and Insurance Mathematics</a></div><br /><div class="event_speaker"><a class="external" href="https://sites.google.com/site/lucianocampi1/">Prof. Dr. Luciano Campi (University of Milan)</a></div><div class="event_title">Mean field coarse correlated equilibria with applications <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />Coarse correlated equilibria are generalizations of Nash equilibria which have first been introduced in Moulin et Vial (1978).

After establishing an existence and approximation results result in a fairly general setting, we develop a methodology to compute mean-field coarse correlated equilibria (CCEs) in a linear-quadratic framework. We identify cases in which CCEs outperform Nash equilibria in terms of both social utility and control levels. Finally, we apply such a methodology to a CO2 abatement game between countries (a slightly modified version of Barrett (1994)). We show that in that model CCEs allow to reach higher abatement levels than the NE, with higher global utility. The talk is based on joint works with F. Cannerozzi (Milan University), F.
