Title: | Categorical approach to discrete harmonic analysis |
Date (JST): | Thu, Feb 07, 2013, 15:30 - 17:00 |
Place: | Seminar Room A |
Abstract: | We show how the problem of finding the local systems on graphs with given dimension of the kernel for discrete Laplace operator leads to noncommutative blow-down and semiorthogonal decompositions of derived categories. We will also describe an interpretation in terms critical points of appropriate functions. |
