Pdf Fixed Points Theorems For N Valued Multifunctions

Pdf Fixed Points Theorems For N Valued Multifunctions A fixed point theorem for compact acylic multifunctions on admissible convex subsets of topological vector spaces, which is a very general result extending a large number of known theorems. We first show that if y is a nonempty ar space and f : y ! y is a compact n valued multifunction, then f has at least n fixed point. we also prove that if c is a nonempty closed convex subset of a topological vector space e and f : c ! c is a.

Pdf Fixed Point Theorems Of Enriched Multivalued Mappings Via Then, there exists a unique fixed point x of the mapping f and x = lim f n p for every p ∈ s. n→∞ mathematics 2021, 9, 3212 5 of 10 the main problem in obtaining a more general f.p.t. is to find those t norms t that are strong enough to guarantee that the sequence of iterates ( f n p)n∈n is a cauchy sequence, and the other is to impose. R. brown, nielsen numbers of n valued fiber maps. j. fixed point theory appl. 4 (2008), 183–201. google scholar r. brown, the lefschetz number of an n valued multimap. jp j. fixed point theory appl. 2 (2007), 53–60. r. brown and j. lin, coincidences of projections and linear n valued maps of tori. J. math 13 (1961), 78 82. by similar techniques two selection theorems are obtained. further, some related results on quasi ordered and partially ordered topological spaces are proved. in particular, a fixed point theorem for order preserving multifunctions on a class of partially ordered topological spaces is obtained. 1. 2. main results. we start with a random fixed point theorem that generalizes significantly theorem 3.1 of itoh [15] which was stated for compact, convex valued continuous multifunctions. so assume that x* is separable too and that k g pfec(x). theorem 1. f:fi x k — p¡c(x) is a multifunction with bounded values s.t.,.

Recently samet, vetro and vetro introduced the notion of α ψ contractive type mappings and established some fixed point theorems in complete metric spaces. in this paper, we introduce the notion. Recently samet, vetro and vetro introduced the notion of α ψ contractive type mappings and established some fixed point theorems in complete metric spaces. in this paper, we introduce the notion of α ∗ ψ contractive multifunctions and give a fixed point result for these multifunctions. we also obtain a fixed point result for self maps in complete metric spaces satisfying a contractive.
