Optimal Small Set Expanders and Their Codes

Tristram Bogart, Marcelo Fiori, Pedro Raigorodsky +1

A left-regular bipartite graph $G$ of degree $d$ is called a $(t, I^\pm)$ -small-set-expander if every subset $X$ of left vertices of size at most $t$ has at least $I^\pm ∣ X ∣$ neighbors. Su…

Mollified Christoffel-Darboux Kernels and Density Recovery on Varieties

Leandro Bentancur, Didier Henrion, Mauricio Velasco

We introduce mollified Christoffel-Darboux (CD) kernels on varieties, a systematic regularization of the classical CD kernel associated with a probability measure on a compact doma…
