Abstract
Given a bounded domain , a result by Bourgain, Brezis, and Mironescu characterizes when a function is in the Sobolev space based on the limiting behavior of its Besov seminorms. We prove a direct analogue of this result which characterizes when a differential -form has a weak exterior derivative , where the analogue of the Besov seminorm that our result uses is based on integration over simplices.
