Buondì, Vi annuncio il seminario di geometria di domani. A presto, Bruno ----- 12-Dec-2019 - 16:15 Sala Seminari (Dip. Matematica) <http://www.dm.unipi.it/webnew/it/aula/sala-seminari-dip-matematica> Splitting numbers <http://www.dm.unipi.it/webnew/it/seminari/splitting-numbers> Carlo Collari NYU Abu Dhabi The weak splitting number is the minimal number of crossing changes which are necessary to split the a link into a collection of disjoint knots. This invariant can be thought of as the (Gordian) distance between a link and the set of completely split links, and somehow as a measure of the complexity of a link. There is another version of the splitting number whose definition allows only crossing changes between different components. In this talk we shall illustrate various methods to compute the weak splitting number and the splitting number. In particular, I shall give a template to produce lower bounds on the weak splitting number, and provide some examples. The material discussed in this talk is joint work with A. Cavallo and A. Conway.

Buondì, Vi annuncio il seminario di geometria di dopodomani. A presto, Bruno ----- 21-Nov-2019 - 16:15 - Sala Seminari (Dip. Matematica) <http://www.dm.unipi.it/webnew/it/aula/sala-seminari-dip-matematica> Geometric finiteness in Hadamard manifolds <http://www.dm.unipi.it/webnew/it/seminari/geometric-finiteness-hadamard-man…> Beibei Liu (MPIM Bonn) In this talk, we will focus on negatively pinched Hadamard manifolds which are complete, simply connected Riemannian manifolds with sectional curvature ranging between two negative constants. We use the techniques in geometric group theory to characterize geometric finiteness from different perspectives, including the geometry of the quotient manifolds, the limit set of the discrete isometry subgroups and so on.

Buondì, Vi annuncio il seminario di geometria di domani pomeriggio, come sempre alle 16.15. A presto, Bruno ---- 14-Nov-2019 - 16:15 Sala Seminari (Dip. Matematica) <http://www.dm.unipi.it/webnew/it/aula/sala-seminari-dip-matematica> Deligne-Mostow lattices and come metrics on the sphere <http://www.dm.unipi.it/webnew/it/seminari/deligne-mostow-lattices-and-come-…> Irene Pasquinelli (Paris Jussieu) Finding lattices in PU(n,1) has been one of the major challenges of the last decades. One way of constructing a lattice is to give a fundamental domain for its action on the complex hyperbolic space. One approach, successful for some lattices, consists of seeing the complex hyperbolic space as the configuration space of cone metrics on the sphere and of studying the action of some maps exchanging the cone points with same cone angle. In this talk we will see how this construction can be used to build fundamental polyhedra for all Deligne-Mostow lattices in PU(2,1).

Could you please pass this message on to any students or others who might be interested? We are looking for someone to start by the middle of 2020; the exact starting date is quite flexible. The closing date for applications is 9 December 2019, and details can be found here: http://jobs.unimelb.edu.au/caw/en/job/901308/research-fellow-in-geometric-t… Best regards, Craig Hodgson and Hyam Rubinstein =============================== RESEARCH FELLOW IN GEOMETRIC TOPOLOGY School of Mathematics and Statistics University of Melbourne Job no: 0049441 Location: Parkville Salary: $72,083 - $97,812 (Level A) plus employer superannuation contributions of 9.5%. This postdoctoral position is associated with the ARC Discovery Project “classical and quantum invariants of low-dimensional manifolds” with Chief investigators Associate Professor Craig Hodgson and Professor Hyam Rubinstein. The successful applicant will participate in all aspects of the project, including the presentation of research results at seminars and conferences, and will, as part of the research team, write scholarly papers for publication in academic journals. The ideal candidate will bring in expertise in geometric topology, hyperbolic geometry and quantum topology, complementing that of Hodgson and Rubinstein. The research project aims to relate quantum invariants arising from physics, including the Jones polynomial and the 3D-index, to classical topology and geometry, including surfaces in 3-manifolds and Thurston's hyperbolic structures on 3-manifolds. To be considered for this position you will have a PhD in mathematics by the date of commencement. You will also have a demonstrated aptitude for research with a sound publication record in relevant areas commensurate with experience and opportunities. This is a full-time, fixed-term position for 2 years. Applications to be submitted by 9 December 2019. The University will only be accepting applications submitted via the MathJobs website https://www.mathjobs.org/jobs ===================

Buondì, Vi annuncio il seminario di geometria di domani, sempre giovedì alle 16.15 in aula seminari. A presto, Bruno P.S.: La settimana scorsa avevo annunciato erroneamente un seminario di Mazzeo; questo sarà invece la settimana prossima. I prossimi seminari sono tutti visibili sul sito del dipartimento. ---- 31-Oct-2019 - 16:15 Sala Seminari (Dip. Matematica) <http://www.dm.unipi.it/webnew/it/aula/sala-seminari-dip-matematica> Metric Lie groups <http://www.dm.unipi.it/webnew/it/seminari/metric-lie-groups> Sebastiano Nicolussi Golo (Università di Padova) The objects of the talk are locally compact metric spaces that are isometrically homogeneous. I will discuss their quasi-isometric classification and the characterization of those spaces that admit dilations. They are not assumed to be length spaces, not even coarsely. ---
