DOI: 10.1007/s10958-019-04311-z
Abstract: We construct a class of polynomials of one complex variable that are pairwise orthogonal with some weight on the boundary of an ellipse. We prove that an arbitrary λ-holomorphic Hölder function defined in an ellipse… read more here.

DOI: 10.1007/s40819-017-0320-x
Abstract: We consider random, skew, N-gons in $$\mathbb {R}^m$$Rm, having zero centroids. We investigate a normalized, midpoint averaging transformation, repeatedly applied to the original polygon, which we identify with a normalized circular convolution modulo N. The… read more here.
