Examples include Hermitian Yang-Mills connections and Kähler-Einstein metrics on the PDE side, and slope stability and K-stability on the algebro-geometric side. I will describe a general framework associating geometric PDEs on complex manifolds to notions of stability, and will sketch a proof showing that existence of solutions is equivalent to stability in a model case. The framework can be seen as an analogue in the setting of varieties of Bridgeland's stability conditions on triangulated categories.<br class=""><br class="">********************************************<br class=""><br class="">講演のZoom URLは開始30分前までに下記ウェブサイトにてお知らせいたします．<br class=""><a href="https://sites.google.com/view/yhashimoto/home/tokyo-tech-geometry-seminar" class="">https://sites.google.com/view/yhashimoto/home/tokyo-tech-geometry-seminar</a><div class="">Googleフォームなどでの事前登録は行いません．<br class=""><br class="">今後のセミナーの予定については，上記ウェブサイト及び以下をご覧ください．<br class=""><a href="http://www.math.titech.ac.jp/page_05.html" class="">http://www.math.titech.ac.jp/page_05.html</a></div><div class=""><br class="">皆様のご参加をお待ちしております．<br class="">どうぞよろしくお願いいたします．<br class=""><br class="">橋本義規<br class="">東京工業大学理学院数学系</div><div class=""><br class=""></div><div class=""><br class=""><div class="">
