Seminario di geometria giovedì (luogo e ora diversi)
by Filippo Bianchi 20 Jun '23

20 Jun '23

Carə tuttə, Vi ricordo che giovedì 22 Giugno si terrà il seminario di Francesco Lin (Columbia University) dal titolo "Homology cobordism and the geometry of hyperbolic three-manifolds". Eccezionalmente, il seminario sarà alle 14.30 in Aula Riunioni. Di seguito l'abstract. A major challenge in the study of the structure of the three-dimensional homology cobordism group is to understand the interaction between hyperbolic geometry and homology cobordism. In this talk, I will discuss how monopole Floer homology can be used to study some basic properties of certain subgroups of the homology cobordism group generated by hyperbolic homology spheres satisfying some natural geometric constraints. Questo seminario sarà l'ultimo del semestre. Vi aspettiamo! Buona giornata, Alice, Filippo e Giuseppe

Title: Persistent homology in action: bridging topology and machine learning, Speaker(s): Davide Moroni, CNR, Pisa, Date and time: 20 Jun 2023, 15:00 (Europe/Rome), Lecture series: Seminar on Combinatorics, Lie Theory, and Topology, Venue: Department of Mathematics (N1). You can access the full event here: https://events.dm.unipi.it/e/196 Abstract -------- Based on recent advances in representations based on topological descriptors, the talk will discuss how to leverage persistent homology for dealing with classification tasks of digital data. Applications to biomedical signal processing will be given (joint work with CNR-IBF and the Department of Surgical, Medical, Molecular Pathology and Critical Area, University of Pisa). -- Indico :: Email Notifier https://events.dm.unipi.it/e/196

Seminario di geometria oggi
by Filippo Bianchi 15 Jun '23

15 Jun '23

Carə tuttə, Scusandomi per il poco preavviso, vi ricordo che oggi 15 Giugno in Aula Seminari alle 11 si terrà il seminario di Marco Moraschini (Università di Bologna) dal titolo "Acyclicity in bounded cohomology". Di seguito l'abstract. Bounded cohomology is an invariant of groups introduced by Johnson in the 70s and then extensively studied both in geometric group theory and in low dimensional topology after the pioneering paper by Gromov (1982). Bounded cohomology is known to vanish in presence of amenable groups, but it is hard to compute for most groups (e.g. we do not know the full bounded cohomology of the non-abelian free group with two generators). In this talk we will introduce bounded cohomology and discuss some recent computations involving boundedly acyclic groups (i.e. groups with trivial bounded cohomology in all positive degrees). We will report some results in collaboration with Francesco Fournier-Facio, Clara Löh and George Raptis. Ricordiamo che le informazioni sui prossimi seminari si trovano sul sito<https://www.dm.unipi.it/categoria-evento/geometry-seminar/>. Il seminario successivo sarà Giovedì 22 Giugno in Aula Seminari alle 11: avremo Francesco Lin (Columbia University), che ci parlerà di "Homology cobordism and the geometry of hyperbolic three-manifolds". Vi aspettiamo! Buona giornata, Alice, Filippo e Giuseppe

postdoctoral fellowship in Bologna
by Martino Lupini 08 Jun '23

08 Jun '23

Dear all, Another post-doctoral fellowship (assegno di ricerca) at the University of Bologna on interactions between topology, homological algebra, and logic has just been advertised. (This is different from the one that was advertised in April!) https://bandi.unibo.it/ricerca/assegni-ricerca?id_bando=66430 This position is co-funded by the Department of Mathematics and the ERC project "Definable Algebraic Topology". The duration of the position is 1 year, with the possibility of being extended up to 3 years. The application deadline is June 23, 2023. Please feel free to forward this information to anyone who might be interested. I will be happy to answer any questions about this opportunity. Best, Martino
