Fixed Point Theory for Weakly Inward Kakutani Maps: the Projective Limit Approach
New fixed point results are presented for weakly inward Kakutani condensing maps defined on a Fréchet space E. The proofs rely on the notion of an essential map and viewing E as the projective limit of a sequence of Banach spaces.
متن کاملSome results on weakly contractive maps
In this paper direct proofs of some common fixed point results for two and three mappings under weak contractive conditions are given. Some of these results are improved by using different arguments of control functions. Examples are presented showing that some generalizations cannot be obtained and also that our results are distinct from the existing ones.
متن کاملA RESULT ON FIXED POINTS FOR WEAKLY QUASI-CONTRACTION MAPS IN METRIC SPACES
In this paper, we give a new fixed point theorem forWeakly quasi-contraction maps in metric spaces. Our results extend and improve some fixed point and theorems in literature.
متن کاملA COMMON FIXED POINT THEOREM FOR $psi$-WEAKLY COMMUTING MAPS IN L-FUZZY METRIC SPACES
In this paper, a common fixed point theorem for $psi$-weakly commuting maps in L-fuzzy metric spaces is proved.
متن کاملPositive Solutions of Some Three-point Boundary Value Problems via Fixed Point Index for Weakly Inward A-proper Maps
in which the second derivative may occur nonlinearly. Positive solutions for the case f (t,u,u′,u′′) = g(t)h(u) have been studied by Ma [15] and Webb [20, 21], when f (t,u,u′,u′′) = h(t,u) by He and Ge [5] and also by Lan [11]. The case f (t,u,u′,u′′) = g(t)h(u,u′) has been studied by Feng [4]. The results in [4, 15] are obtained by means of Krasnosel’skiı̆’s theorem [8], the ones in [5] use Leg...
