The Semester Break activities of the High Dimensional Combinatorics and Expanders Special Year
Combinatorics and more 2018-03-12
UPDATE: Schedule change! An additional workshop On February 5 and shift in dats of the others. Here is the calendar
We have now at HUJI a semester break, but the special semester in High dimensional combinatorics and IIAS leaded by Tali Kaufman and Alex Lubotzky is extremely active.
The Monday program continues during the semester break (Jan 26 to March 18) in the form of “special days”, each devoted to a certain topic. (On a very basic level.)
The first special day, this Monday, January 29, is organized by Anna Gundert and Uli Wagner. The topic is pseudo-randomness. On January 30 there is an Action now day (less basic); on February 05: Stability and property testing February 12: High dimensional Ranom walks day; On February 19: Error correcting codes and high dimensional expanders; on.
I will update about the later special days later.
On Monday, February 12, we will have a special day on “High Dimensional Random Walks” organized by Ron Rosenthal.
11:30-12:30 Ron Rosenthal – Random walks on oriented cells – part I
13:45- 14:45 Izhar Oppenheim – Decomposition Theorem for high dimensional random walks
15:00-16:00 Amitay Kamber – Cutoff of random walks on hyperbolic surfaces and Ramanujan complexes 16:30-17:30 Ron Rosenthal – Random walks on oriented cells – part II
On Monday, February 5, we will have a special day on “Stability and property testing”
organized by Oren Becker.

Place: Room 130, IIAS, Feldman Building, Givat Ram
Program:
10:00-11:00 Oren Becker – The basics of stability and group theoretic prerequisites
11:15-12:15 Tamar Ziegler – Polynomial testing on uniform sets
