In recent years, many SETH-based lower bounds have been proven: for example, n^2 for Edit Distance, 2^n for Hitting Set, 2^{treewidth} for Independent Set. One may speculate that SETH can explain many other current algorithmic barriers. In the talk, we\'ll show that, for many problems, an SETH lower bound would imply new circuit lower bounds.</div><div class="event_time">11:00 &bull; EPF Lausanne, GA 321</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://calendar.google.com/calendar/embed?mode=AGENDA&height=600&wkst=2&bgcolor=%23FFFFFF&src=t36it03v52cus2detrvinlgk18%40group.calendar.google.com&color=%235F6B02&ctz=Europe%2FZurich">Groups, Arithmetic and Algebraic Geometry Seminar </a></div><br /><div class="event_speaker"> Raman Parimala (Emory)</div><div class="event_title">A Hasse principle for projective homogeneous spaces <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />A Hasse principle for projective homogeneous spaces(30 minute general introduction followed by a 45 minute seminar talk, after a short break)  Abstract: A theorem of Harder states that Hasse principle holds for projective homogeneous spaces under connected linear algebraic groups over number fields.

I will report on recent asymptotic results for the characteristic polynomial of these ensembles at general inverse-temperature beta. These asymptotics involve the so-called Sine and Airy processes, as well as a Gaussian log-correlated field, and they should be compared to the classical Plancherel-Rotach asymptotics for the Hermite polynomials (&#946; = &#8734;). The proof are based on the Dumitriu-Edelman tridiagonal representation of the Gaussian beta-ensemble and the transfer matrix method. If time permits, I will also mention some connections to Gaussian multiplicative chaos.

My work so far has investigated the interplay between PDEs and particle systems through the study of two classes of models. The first class is the so-called generalized Dean-Kawasaki equation coming from areas like fluctuating hydrodynamics, mean-field theory and stochastic geometry. The second class is a generalized model for interacting neurons encompassing many of those commonly used in computational neuroscience, in particular in the study of grid cells. For the first model I focus more on the PDE side, while for the second I concentrate on the particle side, where I have given my contributions, respectively. For both models I also present aspects of current and future investigation. Finally, I will discuss other research directions to be pursued in the coming period. </div><div class="event_time">09:00 &bull; EPF Lausanne, Bernoulli Center</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://memento.epfl.ch/event/probability-and-stochastic-analysis-seminar/">Probability (and Stochastic Analysis) Seminar </a></div><br /><div class="event_speaker"> Lukasz Madry (Paris-Dauphine)</div><div class="event_title">Regularisation by fractional noise and the zero noise limit <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />In the talk, I will present the results from my thesis on the limit of zero noise for the singular SDEs driven by the fractional Brownian motion.

The proof uses techniques from regularisation by noise and the study of ergodicity of fractional SDEs, established by Hairer and Panloup-Richard.

The purpose is to provide some alternative perspectives on conditional inference through a notional idealised separation within the minimal sufficient statistic, allowing a geometric account of key ideas from the Fisherian position on conditional inference. The notional idealised separation, in terms an ancillary statistic and what I call a maximal co-ancillary statistic, provides insight and clarifies what is sought from an approximate conditional analysis, where exact calculations may not be available.A parallel framework applies in the Fisherian assessment of model adequacy.Both aspects will be discussed and illustrated geometrically through examples.</div><div class="event_time">15:15 &bull; EPF Lausanne, CM 1 517</div>        </div>      </div>    </div>  </div>  <div id="sms_footer">    address: Alessandra Naldi Windler, Departement Mathematik, HG G 51.4, ETH Zurich, Raemistrasse 101, CH-8092 Zurich<br />    email: <a href="mailto:bulletin@math.ch">bulletin@math.ch</a> | phone: +41 44 632 3684 | url: <a href="https://math.ch">https://math.ch</a>    <br /><br /><img src="//www2.math.ethz.ch/smsjs/sms_logo.gif" width="150" alt="SMS/SMG Logo" title="SMS/SMG Logo" />  </div></div>';
