GENERALIZED MULTIVALUED CONTRACTIONS WHICH ARE QUASI-BOUNDED
GENERALIZED MULTIVALUED CONTRACTIONS WHICH ARE QUASI-BOUNDED
The purpose of this note is to study the following problem: which multivalued generalized contractions are quasi-bounded with the quasi-norm strictly less than 1 ?As consequences, some surjectivity results are given. PreliminariesIf X is a normed space, then an operator / : X -> X is said to be quasi-bounded …
