Contributions To Operator Theory And Applications

Abstract This thesis consists of two parts. The first part deals with existerice and approximation techniques for finding solutions of operator equations or fixed points of operators belonging to certain classes of mappings. The classes of mappings studied include the K-posztz~~dee finzte operators, the suppressive mappings and accretive-type rntippings. In particular, it is proved that for a real Banach space X, the equation Au = f , f E X, where A is a Kpd operator with the same domain�...
