Title: Vector bundles over unordered configuration spaces
</p>
<p class="ql-ed">
Abstract <br />
<p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);" class="ql-font-monospace">I will describe a recent construction of a symmetrized external tensor product of vector bundles of unordered configuration spaces (over some fixed manifold M). Together with the usual tensor product this construction induces a 2-monoidal structure on these vector bundles and naturally appears when trying to construct a geometric model for the multilocal observables in field theory. I will also discuss how equipping the configuration with a certain natural bornology can compensate the fact that they are non-compact, even when the initial manifold M is.</span></p><p><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);" class="ql-font-monospace">based on joint work with Alessandra Frabetti and Olga Kravchenko.</span></p><p class="ql-align-justify"><span class="ql-font-monospace">----</span>-------------------------------------------------------------------------------------------------------------------------</p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span class="ql-font-monospace" style="color: rgb(0, 0, 255); background-color: rgb(246, 246, 246);">We shall open the seminar room at 13.15 for coffee and close the room at 15:00</span></p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span class="ql-font-monospace" style="color: rgb(0, 0, 255); background-color: rgb(246, 246, 246);">Join Zoom Meeting</span></p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><a href="https://cesnet.zoom.us/j/99598413922?pwd=YXNFbk50aVhleXhWSGtISFViLytRU9" rel="noopener noreferrer" target="_blank" class="ql-font-monospace" style="color: rgb(0, 0, 204);">https://cesnet.zoom.us/j/99598413922?pwd=YXNFbk50aVhleXhWSGtISFViLytRU9</a></p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span class="ql-font-monospace" style="color: rgb(0, 0, 255); background-color: rgb(246, 246, 246);">MeetingID:99598413922</span></p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span class="ql-font-monospace" style="color: rgb(0, 0, 255); background-color: rgb(246, 246, 246);">Passcode:Galois</span></p><p class="ql-align-justify"><br></p><p>On the next Wednesday May, 14, <span style="background-color: rgb(255, 255, 255); color: rgb(97, 97, 97);">Giuseppe Bonavolontа from </span></p><p>European Investment Bank, Luxembourg<span style="background-color: rgb(255, 255, 255); color: rgb(97, 97, 97);"> shall give a lecture ``</span><a href="https://www.math.cas.cz/index.php/events/event/3901" rel="noopener noreferrer" target="_blank" style="background-color: rgb(255, 255, 255);">Information Geometry and Quantitative Finance: some applications</a>"</p><p><br></p>
