SUMMARY:Семинар по геометрия на МЦМН
DESCRIPTION:Следващата сбирка на Семинара по геометрия на МЦМН\nще се проведе в сряда\, 15 май 2024 г. от 16:00 ч. в зала 403 и онлайн в Zoom: \nДоклад на тема \nHyperbolic amoebas\n\nще изнесе Михаил Школников\, ИМИ – БАН. \n\n\n\nAbstract: Classical amoebas serve as a tool to study algebraic varieties and as one of the entry points to tropical geometry. The original definition involves a logarithmic projection of a subvariety of a complex algebraic torus\, which can be interpreted as forgetting the phase\, i.e. the arguments of complex numbers. In group-theoretic terms\, this projection map may be thought of as passing to the quotient by the maximal compact subgroup. Suppose one replaces the algebraic torus with a complex three-dimensional matrix group. In that case\, the analogous projection naturally has a three-dimensional hyperbolic space as its target\, and it still makes sense to consider images\, i.e. hyperbolic amoebas\, of complex algebraic varieties under this map. I will review some of the basic properties of hyperbolic amoebas\, extending a fascinating interplay between complex and hyperbolic geometries.Based on joint work with Grigory Mikhalkin. \n\n\nZoom link:\nhttps://us02web.zoom.us/j/83740034721?pwd=VnBtcVpGUktscHQ4a09jZkNZTURyZz09
