Christoffel function on planar domains with piecewise smooth boundary
A. Prymak, O. Usoltseva
We compute up to a constant factor the Christoffel function on planar domains with boundary consisting of finitely many curves such that each corner point of the boundary has…

Pointwise behavior of Christoffel function on planar convex domains
A. Prymak, O. Usoltseva
We prove a general lower bound on Christoffel function on planar convex domains in terms of a modification of the parallel section function of the domain. For a certain class of pl…
