Seminario giovedì

Buondì, Vi annuncio l'ultimo seminario prima delle vacanze, sempre giovedì alle 16.15. A presto e buone feste, Bruno ----- 19-Dec-2019 - 16:15 Sala Seminari (Dip. Matematica) <http://www.dm.unipi.it/webnew/it/aula/sala-seminari-dip-matematica> Contact structures on lens spaces and their Stein fillings <http://www.dm.unipi.it/webnew/it/seminari/contact-structures-lens-spaces-an…> Edoardo Fossati SNS Pisa Everything has been said about Stein fillings of lens spaces when they are endowed with their standard (tight) contact structure. Nevertheless, lens spaces support many more tight structures, that are all classified, but for which a complete list of their Stein fillings is still missing. I will present a series of methods and techniques which can be used to investigate the topology of these fillings, giving constraints, for example, on their Euler characteristic and fundamental group.

Regensburg has a strong research group in low-dimensional and geometric topology, including Jonathan Bowden, Stefan Friedl, Clara Löh, Filip Misev and Raphael Zentner. The c position is initially for 18 months, but will most likely be extended for 6 months more. Starting date is September 1st 2020, or by agreement. Salary is TV-L E13 100%, i.e. roughly 2400 Euro net per month. plus ample travel funding, there are no teaching duties, and no knowledge of German is required. Applications (including a CV, a research statement, and the contact details of two referees in the text of your email) by email to lukas(a)lewark.de. Mid-January, applications will be reviewed until the position is filled. Among equally qualified applicants, preference will be given to applicants from groups that are underrepresented in mathematics. ---------------------------------------------------------------------------- Please contact me by email with any questions you might have.

Seminario domani

11 Dec '19

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.
