Съвместно заседание на Семинара по особености и Семинара на МЦМН

Институт по математика и информатика - БАН Block 8, 1113 БАН IV км., София

Joint meeting of the Seminar on Singularities and the ICMS Seminar, with a lecture by Pablo Cuadrado. The program is as follows. Tuesday, November 18, room 403, IMI-BAS. 13:00 -- Giovane Galindo (ICMS, IMI-BAS) Bundle-type sub-Riemannian structures on holonomy bundles 14:00 -- Pablo Portilla Cuadrado (Universidad Politécnica de Madrid) The medial axis of the Milnor fiber Abstract (Galindo): In this talk we present the notion of Gromov-Hausdorff distance, a novel field of study that aims to understand the topology of the moduli space of Riemannian metrics on a given manifold. We will then present new results on the subject concerning the collapse of principal bundles onto reductive homogeneous spaces. Abstract (Cuadrado): Let f(x,y) define an isolated singularity at the origin. In this talk we explore a [...]

Семинар по особености

Кога и къде: 12.01.2026 г., понеделник, от 14:00 ч. в зала 578 на ИМИ - БАН Докладчик:  Валдемар Цанов (ИМИ - БАН) Заглавие на доклада: Geometry of Milnor fibrations of equivariant plane curves Резюме: The local knot of an irreducible C*-equivariant complex plane curve singularity is a torus knot, and the Milnor fiber is a Seifert surface for this knot. I will describe an explicit universal cover of the Milnor fiber by the hyperbolic plane, using automorphic forms for triangle groups. The characteristic morphism of the Milnor fibration can also be recovered, and used to construct geometric structures by universal covers on the knot complement in the 3-sphere, as well as on the complement of the singular curve in the complex plane.
