---------- Forwarded message --------- From: wagner(a)imj-prg.fr <wagner(a)imj-prg.fr> Date: Mon, Jul 3, 2023 at 3:43 PM Subject: [gdrtresses] Research Fellow in Representation Theory and/or Low Dimensional Topology (one or two positions available) at Leeds. To: gdrtresses(a)listes.math.cnrs.fr <gdrtresses(a)listes.math.cnrs.fr> Research Fellow in Representation Theory and/or Low Dimensional Topology (one or two positions available) at Leeds. We are looking for one or two Postdoctoral Research Fellows to work on the EPSRC Programme Grant: "Combinatorial Representation Theory: Discovering the Interfaces of Algebra with Geometry and Topology". Apply here https://jobs.leeds.ac.uk/Vacancy.aspx?ref=EPSMA1084 The project is led by the 6 Investigators: Professor Karin Baur, principal investigator, together with co-investigators Professor Eleonore Faber, Dr Joao Faria Martins, Professor Bethany Marsh, Professor Paul Martin and Dr Alison Parker. The vision of the Programme Grant is to develop a broad and holistic theory of representation theory, engaging and unifying diverse perspectives, from algebra, geometry and topology to physics, life sciences and engineering, enabling a cross-discipline transfer of ideas. Our aim is thus to develop a unifying representation theory, which acts as a conduit for cross- fertilization between these disciplines. The Programme grant is organised around the Themes, T1 – T4, below: T1. Algebras bridging between combinatorics and geometry; T2. Mutation of algebraic and geometric structures; T3. Algebraic geometry of Grassmannians and moduli spaces; T4. Computations for Physics. For list of Work Packages, including how they are organised into Themes, we refer to our Research Webpage. An ability to work on Theme 1 and / or Theme 4 is preferred for this call. In particular, preference will be given to candidates with expertise in one or more of the following areas: diagram algebras, Hecke algebras, Brauer algebras, homological algebra, algebraic groups, (extended) topological quantum field theory, topological quantum computing, and geometric topology. An ability to work across different work packages, and moreover facility in establishing connections between different themes is a strong plus. The Programme grant is flexible and applications from candidates with the potential to work on any of the themes or work packages will be considered. The Programme Grant team is committed to Equality, Diversity, and Inclusion, and to an environment free of any type of discrimination, and where everyone can reach their full potential. As a group, we will strive to support the career development of the postdoctoral research fellows that we recruit, and to provide them with the optimal environment, including the flexibility, to support their development as the future generation of world-leading researchers. The School of Mathematics also offers a number of family-friendly employment practices that are designed to enable a good work-life balance and to be responsive to support personal circumstances. In many roles we offer flexible working and part-time working, and we have a range of services to help support staff through work and personal challenges. What we offer in return 26 days holiday plus approx.16 Bank Holidays/days that the University is closed by custom (including Christmas) – That's 42 days a year! Generous pension scheme plus life assurance – the University contributes 21.6% of salary. Health and Wellbeing: Discounted staff membership options at The Edge, our state-of-the-art Campus gym, with a pool, sauna, climbing wall, cycle circuit, and sports halls. Personal Development: Access to courses run by our Organisational Development & Professional Learning team, and self-development courses including languages, Creative Writing, Wellbeing Therapies and much more. Access to on-site childcare, shopping discounts and travel schemes are also available. And much more! To explore the post further or for any queries you may have, please contact: Karin Baur, Professor (Principal Investigator) Email: K.U.Baur(a)leeds.ac.uk OR João Faria Martins, Associate Professor (Co-investigator) Email: J.FariaMartins(a)leeds.ac.uk OR Paul Martin, Professor, (Co-investigator) Email: P.P.Martin(a)leeds.ac.uk Apply here https://jobs.leeds.ac.uk/Vacancy.aspx?ref=EPSMA1084

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

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
