Techmath - Math Seminars in Israel
Due to the Corona-virus outbreak the conference is most likely to be postponed.
We will update the website with further information as soon as possible.

After summarizing 1D periodic Jacobi matrices, I will define periodic Jacobi matrices on infinite trees. I'll discuss the few known results and some interesting examples and then discuss lots and lots of interesting conjectures. This is joint work mainly with Nir Avni and Jonathan Breuer but also with Jacob Christensen, Gil Kilai and Maxim Zinchenko.
It is on the spectral theory of a class of operators on trees, for which there has been literature on the random case even in the theoretical physics literature but I am not aware of any application to anything close to real physics so this is probably better as a math talk but I leave it to you to sort it out if you are interested. I don’t care at all which it is called or even if it is jointly sponsored.
Dear colleagues, The preregistration for the conference at the CIRM, in Marseille, 8-12 June 2020, Model Theory: from geometric stability to tame geometry https://conferences.cirm-math.fr/2173.html is open until March 8, 2020. This will be the occasion to celebrate Ehud Hrushovski's 60th birthday and his profound influence on contemporary model theory. Unfortunately due to lack of space, it is possible that not everybody preregistering will be able to come and quite a few of you will be asked to share a double room. We kindly ask you to forward this invitation to anyone you think might be interested and we apologise if you received it multiple times. Best regards, The organizers: Assaf Hasson, Silvain Rideau-Kikuchi, Frank Wagner. The scientific committee: Elisabeth Bouscaren, Antoine Ducros, Dugald MacPherson, Tom Scanlon.
