Fwd: ERC/MSCA Replacement Calls by SNSF
by Stefano Riolo 21 Oct '21

21 Oct '21

Borse post-doc (e altro) in Svizzera Saluti, Stefano -------- Messaggio Inoltrato -------- Due to the participation status of Switzerland as non-associated high-income third country in all 2021-calls for projects of the European Framework Programme for Research and Innovation “Horizon Europe”, Swiss research entities have been excluded from the /ERC Advanced Grants/2021 and the /MSCA European Fellowships 2021/which have now been replaced by two national transitional measures: /*SNSF Advanced Grants*/ The SNSF Advanced Grants <https://www.snf.ch/en/SSHTwon4N4v9R79P/funding/horizon-europe-advanced-gran…> are aimed at leading researchers who wish to conduct innovative, high-risk research in Switzerland. Proposals will be evaluated in two stages by panels of international experts, similar to the panels established for the ERC Advanced Grants Call opened: 1 October 2021 Mandatory pre-registration: 1 November 2021 Submission deadline: 1^December 2021 // /*SNSF Swiss Postdoctoral Fellowships*/ The Swiss Postdoctoral Fellowships <https://www.snf.ch/en/m1NtWp4nTELQixlu/funding/horizon-europe-swiss-postdoc…> (SPF) are research fellowships in all scientific domains with free choice of topic, addressed to researchers who have not resided or carried out their main activity (work, studies, etc.) in Switzerland for more than 12 months in the 36 months immediately prior to the submission deadline. Call opened: 15 October 2021 Mandatory pre-registration: 15 November 2021 Submission deadline: 15^December 2021 Please contact us <mailto:euresearch@unige.ch> for up-to-date information andadvice.

Seminario di Combinatoria, Teoria di Lie e Topologia - Michele D'Adderio - 21 Ottobre 2021
by Francesco Sala 19 Oct '21

19 Oct '21

Carə tuttə, Vi scrivo per annunciarvi che questo giovedì vi sarà un seminario in presenza per il ciclo di seminari "Seminario di Combinatoria, Teoria di Lie e Topologia” di Pisa. Il seminario si svolgerà in Aula Magna dalle 15 alle 16. L'oratore è Michele D'Adderio. — Titolo: Partial and global representations of finite groups Abstract: The notions of partial actions and partial representations have been extensively studied in several algebraic contexts in the last 25 years. In this talk, we introduce these concepts and give a short overview of the results known for finite groups. We will briefly show how this theory extends naturally to the classical global theory, in particular in the important case of the symmetric group. This is joint work with William Hautekiet, Paolo Saracco, and Joost Vercruysse. — (Qualora pensiate di venire, per aiutarmi nella stesura del documento di tracciamento, vi prego di iscrivervi qui) Vi prego di inoltrare questo messaggio a tutti coloro che ritenete possano essere interessati. Sperando di vedervi numerosi, vi mando i miei saluti, Francesco

Seminario di geometria algebrica e aritmetica di Pisa, 13 ottobre
by Tamas Szamuely 12 Oct '21

12 Oct '21

Cari tutti, il seminario di geometria algebrica e aritmetica riprende in presenza! Prossimo seminario: Mercoledì 13 ottobre 2021, Dipartimento di matematica, Aula Magna 16:00--17:00 Gregory Pearlstein (Pisa): Archimedean height pairings for higher cycles By the work of Richard Hain, the archimedean height pairing on ordinary algebraic cycles can be interpreted as an invariant of an associated mixed Hodge structure. In this talk, we will present a similar construction for higher cycles in the Bloch complex. Families of higher cycles produce admissible variations of mixed Hodge structure. We will describe the asymptotic behavior of the height pairing in the case where the associated variation of mixed Hodge structure is Hodge-Tate. This is joint work with J. Burgos Gil and S. Goswami.

Fwd: Seminario di Combinatoria, Teoria di Lie e Topologia - Giovedì 7 Ottobre - 3 pm

Inoltro avviso su un seminario in dipartimento, domani alle 15. Bruno ---------- Forwarded message --------- From: Francesco Sala <francesco.sala(a)unipi.it> Date: Mon, Oct 4, 2021 at 10:51 PM Subject: Seminario di Combinatoria, Teoria di Lie e Topologia - Giovedì 7 Ottobre - 3 pm To: Carə tuttə, Vi scrivo per annunciarvi che questo giovedì riprenderà in presenza il ciclo di seminari "Seminario di Combinatoria, Teoria di Lie e Topologia” di Pisa. Il seminario si svolgerà in Aula Magna dalle 15 alle 16. La prima oratrice è Viola Siconolfi, appena giunta a Pisa. — Titolo: Ricci curvature, graphs and Coxeter groups Abstract: I will talk about a notion of curvature for graphs introduced by Schmuckenschläger which is defined as an analogue of Ricci curvature. This quantity can be computed explicitly for various graphs and allows to find bounds on the spectral gap of the graph and isoperimetric-type inequalities. I will present some general results on the computation of the discrete Ricci curvature of any locally finite graph. I will then focus on graphs associated with Coxeter groups: Bruhat graphs, weak order graphs and Hasse diagrams of the Bruhat order. — (Qualora pensiate di venire, per facilitarmi la stesura del documento di tracciamento, vi prego di iscrivervi qui <https://doodle.com/poll/hwuxn6a7p7sqdu4i?utm_source=poll&utm_medium=link>) Vi prego di inoltrare questo messaggio a tutti coloro che ritenete possano essere interessati.

Fwd: [Utenti] annuncio minicorso: "Combinatorial topology and group theory" / riunione preliminare
by Bruno Martelli 04 Oct '21

04 Oct '21

Segnalo minicorso in topologia presso il nostro dipartimento (on line) Bruno ---------- Forwarded message --------- From: Coordinatore del dottorato in matematica <coord_mat(a)dm.unipi.it> Date: Sat, Oct 2, 2021 at 9:14 PM Subject: [Utenti] annuncio minicorso: "Combinatorial topology and group theory" / riunione preliminare To: mailing list dottorandi <dottorandi(a)mail.dm.unipi.it>, utenti(a)dm.unipi.it <utenti(a)dm.unipi.it> Cc: Giovanni Paolini <paolini(a)caltech.edu> Buonasera, nel mese di novembre Giovanni Paolini (Caltech) terrà un mini-corso di 5 lezioni dal titolo Combinatorial topology and group theory (vedere sotto per maggiori dettagli). Il corso sarà tenuto online. La riunione preliminare sarà il 4 novembre 2021, ore 17 – 18, su Google Meet: https://meet.google.com/fgj-yduu-kpf Giovanni Alberti ============== Titolo: Combinatorial topology and group theory Abstract: In this course, we will cover combinatorial techniques to study topological spaces and groups. On the topological side, we are going to see how discrete Morse theory can be used to prove homotopical and homological statements through the language of partially ordered sets (posets). On the group-theoretic side, we are going to introduce Garside theory and apply it to the study of symmetric groups and braid groups (as well as their generalizations, Coxeter and Artin groups). Using discrete Morse theory, we will prove one of the main results of Garside theory, namely the construction of a classifying space (or K(π,1)) for an arbitrary Garside group. We will also mention algorithmic aspects in discrete Morse theory (related to collapsibility) and in Garside theory (the word problem). If time permits, we will also touch on current research directions in the theory of Garside groups, Coxeter groups, and Artin groups. Prerequisiti: Basic algebraic topology and homological algebra (e.g., the UniPi courses "Elementi di topologia algebrica" and "Istituzioni di algebra"). Emanuele Delucchi's course on "Combinatorial methods in topology" (Spring 2021) is not a requirement but will be useful. Programma provvisorio in 5 lezioni: 1. Partially ordered sets and relevant examples 2. Topological discrete Morse theory, applications and algorithms 3. Algebraic discrete Morse theory 4. Combinatorial Garside structures, the word problem, and examples (symmetric groups and braid groups) 5. Classifying spaces of Garside groups and consequences -- ________________________________________________________ Prof. Giovanni ALBERTI coordinatore del dottorato in Matematica Università di Pisa director of the graduate program in Mathematics University of Pisa e-mail: coord_mat(a)dm.unipi.it phone: +39 050 2213 239 virtual office: https://meet.google.com/rmt-jyke-iyw webpage: http://www.dm.unipi.it/webnew/dottorato/phd ________________________________________________________ _______________________________________________ Utenti mailing list Utenti(a)fields.dm.unipi.it https://fields.dm.unipi.it/listinfo/utenti
