Given a subset D of the Euclidean space, we study nonlocal quadratic forms that take into account tuples (x,y)∈D×D\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(x,y) \in D \times D$$\end{document} if and only if the line segment between x and y is contained in D. We discuss regularity of the corresponding…
