They assign to an oriented surface with an embedded graph and a finite-dimensional semisimple Hopf algebra a vector space, the ground state, that is independent of the graph. It is the vector space the Turaev-Viro TQFT assigns to the surface and carries an action of the mapping class group. We give a simple description of mapping class group actions in the quantum double model with and without boundary. We then show how the quantum double model and the associated mapping class group actions can be generalised to involutive Hopf monoids in complete and cocomplete symmetric monoidal categories. This allows for interesting examples that cannot be treated in the framework of TQFTs. This is joint work with Thomas Voß and Anna-Katharina Hirmer. </div><div class="event_time">15:30 &bull; Université de Genève, Conseil Général 7-9, Room 1-07</div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Wednesday, April 3      </div>      <div class="day_content">        <div class="day_content_item normal"><div class="event_location uni_ba"><a class="external" href="https://unibas.ch">Universität Basel</a></div><div class="event_type"><a class="external" href="https://dmi.unibas.ch/de/forschung/mathematik/analysis/analysis-seminar">Analysis Seminar</a></div><br /><div class="event_speaker"> Vikram Giri (ETH Zürich)</div><div class="event_title"><a class="external" href="https://dmi.unibas.ch/de/news-events/detail/seminar-analysis-and-mathematical-physics-vikram-giri-eth-zuerich/">Newton-Nash iterations in PDE</a> <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />A common issue in convex integration methods (going back to Nash) is the presence of unwanted high-high frequency interactions. These issues can prevent the methods from producing solutions with the optimum "Onsager" regularity to a given system of PDEs. We will discuss these issues in the setting of the 2D Euler equations and then discuss a linear Newton iteration designed to get rid of these unwanted interactions in this setting. We will conclude by discussing applications to other PDEs. This is based on joint works with Razvan-Octavian Radu and Mimi Dai.</div><div class="event_time">14:15 &bull; Universität Basel, Spiegelgasse 5, Seminarraum 05.002</div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Thursday, April 4      </div>      <div class="day_content">        <div class="day_content_item no_event">        No events scheduled today!        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Friday, April 5      </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>';
