2013/2014 The Equality of Mixed Partial Derivatives
Ettore Minguzzi
Real Anal. Exchange 40(1): 81-98 (2013/2014).

Abstract

We review and develop two little-known results on the equality of mixed partial derivatives, which can be considered the best results so far available in their respective domains. The former, due to Mikusiński and his school, deals with equality at a given point, while the latter, due to Tolstov, concerns equality almost everywhere. Applications to differential geometry and General Relativity are commented.
