THE CONDENSATION EXTENSION AND THEMULTIPLE POSITIVE FIXED POINTSOF THE CONDENSING MAPPING

摘要

In the paper the authors present some formulae to the condensation extension and k-set contractive extension of a condensing mapping and a k-set contractive mapping respectively, and obtain the sufficient conditions for a condensing mapping to have two or three fixed points. At last they apply their results to solve the generalized H-equation and two-points boundary value problems.
