Inoltro avviso di RTD A a Roma in geometria. Ciao, Bruno ---------- Forwarded message --------- From: Gm Gm <gabriele.mond(a)gmail.com> Date: Thu, Oct 4, 2018 at 2:04 PM Subject: Precall: 1 position as 3-year postdoc in geometry in Rome To: Dear all, my department (Sapienza, Mathematics) is about to open a call for a 3-year postdoc (RTD-A) in geometry. The position has light teaching load (1 course per year). Details will appear in the formal call. Usually, at the expiration of such contract a new call for a tenure-track associate professor (RTD-B) will be opened. This is intended to give the opportunity to the postdoc to become tenure-track, though this new call is completely independent of the former one (and a different person could well be hired). Please inform any potential candidate. Thank you! Gabriele Mondello

Inoltro avviso di post-doc in topologia in bassa dimensione Bruno ---------- Forwarded message --------- From: <greg.mcshane(a)gmail.com> Date: Fri, Sep 28, 2018 at 9:48 PM Subject: [gdrtresses] 2 year postdoc in low dimensional topology, LMNO (Université de Caen) To: <gdrtresses(a)listes.math.cnrs.fr> Dans le cadre du projet ARTIQ (https://artiq.lmno.cnrs.fr) un postdoc de 24 mois en Topologie en basse dimension est à pourvoir au LMNO (Université de Caen) à partir du 1er février 2019. Des possibles thèmes de recherche sont: groupes de tresses et leur généralisations, algèbres de Temperley-Lieb et théorie des noeuds. Des compétences en combinatoire, théorie des catégories et/ou calcul diagrammatique seront particulièrement appréciées. Le but de ce recrutement est de renforcer les interactions entres les équipes GRAAL (LMNO) et C&A (LITIS, Université de Rouen): en particulier le postdoc participera aux activités d'un groupe de travail commun en Topologie et informatique quantique. Plus d'informations sont disponibles sur la page web du projet, https://artiq.lmno.cnrs.fr. Pour candidater il faut envoyer un CV, une liste de publications et un court projet de recherche à paolo.bellingeri(a)unicaen.fr avant le 1er décembre 2018. Within the framework of ARTIQ project (https://artiq.lmno.cnrs.fr) a 24 months postdoc in low dimensional Topology based at LMNO (Laboratory of Mathematics Nicolas Oresme, University of Caen) will be available starting from 1st of February 2019. Possible topics are: braid groups and generalizations, Temperley-Lieb algebras and knot theory. Skills in combinatorics, category theory and diagrammatic calculus will be particularly appreciated. The main goal of this recruitment is to strengthen the relationship between the GRAAL (LMNO) and C&A (LITIS, University of Rouen) teams: to this purpose, the postdoc will participate to a joint working group on Topology and Quantum Informatics. More informations are available at https://artiq.lmno.cnrs.fr. To apply please send a CV, a list of publications, and a short research project to paolo.bellingeri(a)unicaen.fr before the 1st of December 2018.

Seminario giovedì
by Bruno Martelli 01 Oct '18

01 Oct '18

Buondì, Vi segnalo il seminario di geometria di giovedì prossimo (ore 16 aula seminari). Siete tutti invitati, A presto, Bruno Martelli Thursday, October 4, 2018 16:00 17:00 SEMINARI DI GEOMETRIA Sala Seminari (Dip. Matematica) Transverse invariants from the deformations of Khovanov sl_3 homology Carlo Collari In this talk I will describe some invariants for transverse links in S^3 (endowed with the symmetric contact structure) arising from the deformations of Khovanov sl_3 homology. I will start with a brief introduction to the theory of transverse links in S^3. Afterward, I will recall some known results concerning transverse invariants in link homologies. In particular, I will focus on the invariants coming from Khovanov-Rozansky homologies, and those coming from the deformations of Khovanov homology. After the introductory part, I will briefly describe the construction and the properties of the universal sl_3 link homology, due to Mackaay and Vaz, and define the transverse invariants. These invariants, which are called the \beta_3-invariants, are cycles in the universal sl_3 complex. Finally, I will state a result concerning the vanishing of the homology classes of these invariants, and compare it with similar results known for other invariants. The idea of the proof will be also given. Time permitting, I will also give a number of Bennequin-type inequalities which can be proved using the \beta_3-invariants.
