[GeCo GeDi seminar] Topological Quantum Field Theories

Topological Quantum Field Theories ----------------------------------------- http://gecogedi.dimai.unifi.it/seminar/194/ Date: Wednesday, Mar 11, 2015 Time: 18:00 Place: Sala Seminari, Dipartimento di matematica, Pisa Speaker: Carlo Collari Seminari dei Baby-Geometri Abstract. Topological Quantum Field Theories (TQFTs for short) were axiomatized by Atiyah in 1988 ([1]). Following his exposition, we will define the concept of TQFT and give some examples. In particular, we will describe the (1+1)-TQFTs and their algebraic counterparts, the Frobenius algebras. Time permitting we will give some more examples in higher dimension. [1] M. Atiyah, /Topological Quantum Field Theory/, Publications Mathématiques de l'IHÉS 68 (68): 175–186

buondì, vi segnalo il seminario di geometria di domani, sempre alle 16 in aula seminari. a presto, Bruno ------- SEMINARI DI GEOMETRIA Wednesday, February 18, 2015 Ora Inizio: 16:00 Aula: Sala Seminari (Dip. Matematica) Relatrice: Cristina Pagliantini (Regensburg) Titolo: Quasimorfismi e coomologia limitata Abstract: Nel seminario presenteremo la relazione tra coomologia limitata e quasimorfismi di un gruppo. Ci concentreremo poi sui quasimorfisimi mediani e daremo una caratterizzazione delle azioni su alberi che inducono quasimorfismi mediani non banali.

buondì, segnalo con colpevole ritardo il seminario di geometria di oggi, sempre in aula seminari alle 16. Bruno Martelli ---- SEMINARI DI GEOMETRIA Titolo: Relative bounded cohomology for groupoids Wednesday, February 11, 2015 Ora Inizio: 16:00 Ora Fine: 17:00 Aula: Sala Seminari (Dip. Matematica) Relatore: Matthias Blank (Regensburg) Bounded cohomology is a functional analytic modification of regular cohomology, with applications to geometry, topology and (geometric) group theory. After giving a very short introduction to groupoids, I will present our construction of (relative) bounded cohomology for (pairs) of groupoids. This includes a natural setting for bounded cohomology relative to a family of subgroups. Finally, I will discuss a relative version of Gromov's mapping Theorem in this context.

buondì, vi annuncio un seminario di geometria di oggi alle 16. Bruno ---- SEMINARI DI GEOMETRIA Titolo: DECOMPOSITION OF QUANTUM REPRESENTATIONS INTO IRREDUCIBLE FACTORS Wednesday, January 28, 2015 Ora Inizio: 16:00 Ora Fine: 17:00 Aula: Sala Seminari (Dip. Matematica) Relatore: Julien Korinman (Université de Grenoble) Abstract: I will define two families of representations of the mapping class group of surfaces, namely the Weil and Reshetikhin-Turaev representations. Then I will state some results concernings the (in)finiteness of their image and their decomposition into irreducible factors.

PhD and post-doc positions in Utrecht
by Roberto Frigerio 21 Jan '15

21 Jan '15

Ricevo e inoltro. Roberto I would like to draw your attention to several PhD and PostDoc positions that we have available here at Utrecht University. The positions are associated to one of my research projects; the project is rooted in Poisson Geometry, but rapidly exceeds the boundaries of Poisson Geometry to neighboring areas. Therefore the need of man power with expertise in various parts of Geometry. To be a bit more specific, I am looking for: - PhD candidates with a good background in Differential Geometry/Topology. We have 2-3 such positions to be filled in 2015 or 2016. These are standard, 4 years PhD positions at Utrecht University. - PostDoc candidates whose expertise comes with one of the following key-words: contact geometry, low-dimensional topology, K3 surfaces and Kahler geometry, hyperkahler geometry, Lefschetz fibrations (classical as well as variations, up to broken ones), open-book decompositions, symplectic geometry/topology, toric geometry, moment maps, geometric aspects of gerbes, integral affine geometry, nil and solv-manifolds, the standard conjectures from affine geometry (Auslander conjecture, Markus conjecture), foliations and leafwise geometric structures, G-structures and the geometry of PDEs. We have 2-3 such PhD positions, they are for 2-3 years and they come with very low teaching duties (if at all). If you want to see more details, or you wonder how all these are related to each other (through Poisson geometry), you can find a more detailed description at: http://www.staff.science.uu.nl/~crain101/positions Can you please forward this information to anyone who may be interested? The deadline for applying if February 15, 2015 (in case that not all positions will be filled, there will be another round later in the year). More details, including the ones on how to apply, can be found at the same address: http://www.staff.science.uu.nl/~crain101/positions Thank you. Best regards, Marius Crainic
