In 2012, E. Hawkins proposed a realization of this programfor geometric quantization of polarised observables in particular, usingthe deformation to normal cone. In this scheme, polarization is requiredto satisfy certain assumptions. However, Bonechi, Ciccoli et al gaveexamples of rather singular polarizations on the Podles sphere and complexprojective space. In this talk we discuss a reformulation of Hawkins\'scheme which accommodates singular polarizations. This is joint work withF. Bonechi, N. Ciccoli, V. Zenobi and P. Antonini.</div><div class="event_time">13:30 &bull; ETH Zentrum, Winterthurerstrasse 190, Z&uuml;rich, Building Y27, Room H 25</div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Tuesday, July 8      </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">        Wednesday, July 9      </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">        Thursday, July 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://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"> Jihao Liu (Peking University)</div><div class="event_title">Title T.B.A.</div><div class="event_time">14:00 &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/schools/sb/research/math/statistics-seminars/">Statistics Seminar </a></div><br /><div class="event_speaker"> Riccardo  Passeggeri (Imperial College)</div><div class="event_title">Random signed measures <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />Point processes and, more generally, random measures are ubiquitous in statistics. However, they can only take positive values, which is a severe limitation in many situations. In this presentation, we introduce random signed measures, also known as real-valued random measures, and apply them to construct various Bayesian non-parametric models.In particular, we provide an existence result for random signed measures, allowing us to obtain a canonical definition for random signed measures and solve a long-standing open problem.Further, we provide a representation of completely random signed measures (CRSMs), which extends the celebrated Kingman\'s representation for completely random measures (CRMs) to the real-valued case. We then introduce specific classes of random signed measures, including the Skellam point process, which plays the role of the Poisson point process in the real-valued case, and the Gaussian random measure. We use the theoretical results to develop two Bayesian nonparametric models -- one for sentiment topic modeling and the other for random graphs -- and to investigate mean function estimation in Bayesian nonparametric regression.</div><div class="event_time">15:15 &bull; EPF Lausanne, CM 1 1000</div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Friday, July 11      </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>';
