Several characterizations about preinvex fuzzy mapping are obtained in this paper. Firstly, an equivalent condition of preinvex fuzzy mapping is established under certain conditions. Furthermore, the necessary and sufficient conditions for differentiable and twice differentiable preinvex fuzzy mappi

Recently I proved the following theorem: To every positive integer m there exists a positive integer h such that the following holds: If S is a set of h elements and f a mapping of the power set q of S into q such that f(T) E T for all TE 8, then there exists a strictly increasing sequence T, c l l
The concept of upper and lower semicontinuity of fuzzy mappings introduced by Bao and Wu [Y.E. Bao, C.X. Wu, Convexity and semicontinuity of fuzzy mappings, Comput. Math. Appl., 51 (2006) 1809-1816] is redefined by using the concept of parameterized triples of fuzzy numbers. On the basis of the line
Let K be a nonempty closed convex subset of a Banach space E, T : K โ K a continuous pseudo-contractive mapping. Suppose that {ฮฑ n } is a real sequence in [0, 1] satisfying appropriate conditions; then for arbitrary x 0 โ K , the Mann type implicit iteration process {x n } given by x n = ฮฑ n x n-1 +
