The weekly colloquium features a talk by an invited speaker. Topics vary and include all areas of mathematics.

The colloquium takes place on Tuesdays, 14:00 in room 614, 6’th floor of the Science and Education Building. For further details, please contact the colloquium coordinator, Dr. Nadav Yesha.

Colloquium: Monday, January 1, 4 pm. Speaker: Nadav Yesha (King’s College). Title: “CLT for small scale mass distribution of toral Laplace eigenfunctions”.

In this talk we discuss the fine scale $L^2$-mass distribution of toral Laplace eigenfunctions with respect to random position. For the 2-dimensional torus, under certain flatness assumptions on the Fourier coefficients of the eigenfunctions and generic restrictions on energy levels,…

Colloquium: Monday, November 27, 4 pm. Speaker: Stuart W. Margolis (Bar Ilan). Title: “CW-decompositions, Leray numbers and the representation theory and cohomology of left regular band algebras”.

Over the last 15 years, it has been noted that many combinatorial structures, such as real and complex hyperplane arrangements, interval greedoids, matroids, oriented matroids, and others have the structure of a left regular band, a certain kind of finite monoid….
