Title: Geometry through the Lens of dg Manifolds
</p>
<p class="ql-ed">
Abstract <br />
<p class="ql-align-justify">Differential graded (dg) manifolds, or $Q$-manifolds, provide a powerful framework for unifying diverse structures in modern geometry. </p><p class="ql-align-justify">By equipping a graded supermanifold with an odd homological vector field $Q$ (satisfying $Q^2 = 0$), we obtain a robust language </p><p class="ql-align-justify">capable of "taming" complex geometric problems. In this talk, I will demonstrate the versatility of the dg-framework by exploring </p><p class="ql-align-justify">its underlying geometry and its applications across several domains, specifically focusing on how it characterizes complex structures </p><p class="ql-align-justify">and foliations.</p><p class="ql-align-justify"><br></p><p class="ql-align-justify">-------------------------------------------------------------------------------------------------------------------------------------</p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255);">We shall open the seminar room and ZOOM meeting at 13.15 for coffee and close ZOOM at 15.30</span></p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255);">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=YXNFbk50aVhleXhWSGtISFViLytRUT09" rel="noopener noreferrer" target="_blank" style="background-color: rgb(255, 255, 255); color: rgb(17, 85, 204);">https://cesnet.zoom.us/j/99598413922?pwd=YXNFbk50aVhleXhWSGtISFViLytRUT09</a></p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255);">Meeting ID:99598413922</span></p><p class="ql-align-justify"><span style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255);">Passcode:Galois</span></p><p class="ql-align-justify"><br></p><p class="ql-align-justify"><span style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255);">---------------------------------------------------------------------------</span></p><p><span style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255);">On Wednesday, April 22</span>, Pierre Bieliavsky<span style="color: rgb(34, 34, 34); background-color: rgb(255, 255, 255);"> shall give a talk on </span><a href="https://www.math.cas.cz/index.php/events/event/4129" rel="noopener noreferrer" target="_blank" style="color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);"><strong>Kinematical Lie algebras and symplectic symmetric spaces</strong></a></p><p class="ql-align-justify"><br></p><p><br></p>
