In joint work with R. Bezrukavnikov, M. McBreen and Z. Yun, we construct analogues of these spaces for homogeneous affine Springer fibers. We further understand the categories of microlocal sheaves in these symplectic spaces supported on the affine Springer fiber as some categories of coherent sheaves. In this talk I will mostly focus on the case of the homogeneous element ts for s a regular semisimple element and will discuss some relations of these categories with the small quantum group providing a categorification of joint work with R.Bezrukavnikov, P. Shan and E. Vasserot.  </div><div class="event_time">15:30 &bull; Université de Genève, Conseil Général 7-9, Room 1-05</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"> Peter Sarnak (Princeton)</div><div class="event_title">Title T.B.A.</div><div class="event_time">16:15 &bull; EPF Lausanne</div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Wednesday, June 10      </div>      <div class="day_content">        <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.unil.ch/dsa/en/home/menuinst/seminaires--evenements/research-seminars.html">Talks in Actuarial Mathematics </a></div><br /><div class="event_speaker"> Nikolai  Kriukov  (University of Amsterdam)</div><div class="event_title">Functional Central Limit Theorem for the simultaneous subgraph count of dynamic Erd\\H{o}s-R\\\'{e}nyi random graphs <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br /> In this talk we consider a dynamic Erd\\H{o}s-R\\\'{e}nyi random graph with independent identically distributed edge processes.

Specifically, we want to approximately maximize a monotone submodular function over vertices vi sited in the walk and bound the repetition of vertices in the walk. We also discuss an application in the problem of maximizing monotone submodular functions over perfect matchings in bipartite graphs.The algorithm is based on a recursive randomized rounding procedure over a Sherali-Adams extended formulation.This is upcoming joint work with Rico Zenklusen. </div><div class="event_time">11:00 &bull; EPF Lausanne, MA B1 524</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/daco-seminar">DACO Seminar</a></div><br /><div class="event_speaker"> Anouk Brose (University of California, Davis, US)</div><div class="event_title">Lattice Diameters of Polytopes <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />The lattice diameter of a polytope measures the maximum number of collinear lattice points in a polytope, equivalently, the maximum number of lattice points in a one-dimensional section of a polytope. We study structural properties of the lattice diameter and show connections to the shortest vector problem and the lattice width of a polytope. Algorithmically, we give a fixed-dimension polynomial time algorithm that computes the lattice diameter of a rational polytope, and show that this problem is NP-hard when the dimension is non-fixed. Furthermore, we study how segments attaining the lattice diameter behave under dilation of the polytope and prove an Ehrhart-theory type result. This is joint work with G. Averkov, J.A. De Loera, G. Lopez-Campos, and A.

They were introduced by Chermak to study the p-local structure of finite groups and come equipped with a "domain," which consists in the set of words for which the product is defined. At first glance, given a fixed set X, it may seem possible to define infinitely many partial group structures on X by varying the domains, even while ensuring that all these structures have coherent products. For example, if G is a finite group, one might expect that there could be infinitely many different partial group structures "contained" in G by selectively removing sets of words from the domain.However, in a joint work with Philip Hakney, we show that finite partial groups are truly finite objects: they can be defined using only a finite set of data and, in particular, contain only finitely many "partial subgroups." This follows from the fact that finite partial groups have finite dimension as symmetric sets.During the talk, we will explore both the algebraic and topological approaches to partial groups and no prior knowledge of the topic will be assumed.</div><div class="event_time">10:00 &bull; <a class="external" href="https://plan.epfl.ch/?room==CM%201%20517">EPFL Lausanne</a></div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Friday, June 12      </div>      <div class="day_content">        <div class="day_content_item no_event">        No events scheduled today!        </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>';
