Recent studies of integrable systems (e.g. Hitchin systems, Beauville-Mukai systems) suggest two common features of the perverse filtration of abelian fibrations:1) the perverse filtration is multiplicative with respect to the cup product;2) the perversity of tautological classes is governed by the Chern degree.In this talk, I will explain a unified approach to both 1) and 2) for a natural class of abelian fibrations, namely fibrations in compactified Jacobians. I will discuss several ingredients from (coherent) derived categories, K-theory/Chow theory, and constructible categories, as well as some applications of our result. Joint work in progress with Davesh Maulik and Junliang Shen.</div><div class="event_time">16:00 &bull; ETH Zentrum, Building ITS, Room  </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>';
