Admissible maps, intersection results, coincidence theorems [PDF]

, 2001
summary:We obtain generalizations of the Fan's matching theorem for an open (or closed) covering related to an admissible map. Each of these is restated as a KKM theorem.

A localized version of Ky Fan’s minimax inequality

Nonlinear Analysis: Theory, Methods & Applications, 1999
The celebrated Ky Fan's minimax inequality concerns a convex compact set \(K\) in some normed space, and a bivariate function \(f: K\times K\to R\). The authors establish an equivalent version of Ky Fan's result, but which has a ``local'' flavor: it involves the tangent cone to \(K\) and a certain type of Clarke's generalized derivative of \(f\).
