Speaker: 

Yotam Dikstein (Weizmann Institute of Science)

In this talk we give an alternative characterization for high dimensional expanders through high dimensional random walks. We will describe the Up and Down operators, and show a spectral condition on them that is equivalent to link expansion. We will discuss an approximate Fourier decomposition for functions on high dimensional expanders.
