SUMMARY:Общ семинар на секция "Анализ\, геометрия и топология" и МЦМН
DESCRIPTION:Съвместна сбирка на семинара на МЦМН и семинара “Анализ\, геометрия и топология” в ИМИ\, София\, ще се проведе идния вторник\, с доклад на Elia Fusi\, както следва.\n\nВторник\, 22-ри юли\, 13:00 часа\, зала 403 на ИМИ-БАН.\nElia Fusi\, University of Torino:\nSpecial metrics in hypercomplex geometry\n\nAbstract:The existence of special hyperHermitian metrics plays an important role in the study of hypercomplex manifolds. In this talk\, after a brief overview of the basic definitions in hypercomplex Geometry\, we will discuss two of the main types of special metrics in the hypercomplex setting: quaternionic Gauduchon and strong HKT metrics. First of all\, we will discuss sufficient and equivalent conditions for a quaternionic Gauduchon metric to exist.  Afterwards\, we will show that strong HKT and balanced hyperHermitian metrics cannot coexist on a compact non-hyperKähler manifold\, proving a particular instance of the Fino-Vezzoni conjecture. Finally\, we will introduce an Einstein condition for hyperHermitian metrics and describe the similarities with the Kähler-Einstein case.\nThis is a joint work with Giovanni Gentili.\n \nПовече информация можете да намерите на страницата на семинара:\nhttps://icms.bg/category/icms-seminar/\n
