in this paper, existence theorems for the fuzzy volterra-fredholm integral equations of mixed type (fvfiemt) involving fuzzy number valued mappings have been investigated. then, by using banach's contraction principle, sufficient conditions for the existence of a unique solution of fvfiemt are given. finally, illustrative examples are presented to validate the obtained results.

Random Feature mappings as first suggested in 2007 by Rahimi and Recht provide mappings that closely approximate feature spaces in O(nDd). Two new approaches for random feature mapping were presented in 2013. ”Fastfood” replaces the random matrix of Rahimi and Recht with an approximation that uses the Walsh-hadamard transform to gain significant speed and storage advantages. It promises to crea...

Huang and Zhang 1 generalized the notion of metric space by replacing the set of real numbers by ordered Banach space, deffined a cone metric space, and established some fixed point theorems for contractive type mappings in a normal cone metric space. Subsequently, several other authors 2–5 studied the existence of common fixed point of mappings satisfying a contractive type condition in normal...

Let (X, d) be a complete convex metric space, and C be a nonempty, closed and convex subset of X. We consider Ćirić type contractive self-mappings T of C satisfying: d(Tx, Tx) ≤ a max {d(x, y), c[d(x, Ty) + d(y, Tx)]} + b max {d(x, Tx), d(y, Ty)}, for all x, y ∈ C, where 0 < a < 1, a + b = 1, and c ≥ 0. We give a simple proof to an extension of Ćirić’s fixed point theorem [4] and Gregus’ fixed ...

Abstract This paper aims to present the concept of multi-valued mappings in fuzzy cone metric spaces and prove some basic lemmas, a Hausdorff metric, fixed point results for set-valued cone-contraction mappings. We theorem rational type cone-contractions spaces. Our extend improve given literature.

In this paper, we introduce a new sequential space as generalization of M − metricspaces and b metric spaces. generalized define two contractive mappings namely m contraction quasi-contraction prove some fixed point theorems for such type mappings. Several illustrative examples have been presented in strengthening the hypothesis our theorems.

Several Ising-type magnetic van der Waals (vdW) materials exhibit stable ground states. Despite these clear experimental demonstrations, a complete theoretical and microscopic understanding of their anisotropy is still lacking. In particular, the validity limit identifying one-dimensional (1-D) Ising nature has remained uninvestigated in quantitative way. Here we performed mapping for prototypi...

In [26], Olofsson introduced a kind of second order homogeneous partial differential equation. We call the solution this equation real kernel ?-harmonic mappings. paper, we study some geometric properties give univalence criteria and sufficient coefficient conditions for mappings that are fully starlike or convex ?, ? [0, 1). Furthermore, establish Landau type theorem

In this paper, using the concept of attractive points of a nonlinear mapping, we obtain a strong convergence theorem of Halpern’s type [6] for a wide class of nonlinear mappings which contains nonexpansive mappings, nonspreading mappings and hybrid mappings in a Hilbert space. Using this result, we obtain well-known and new strong convergence theorems of Halpern’s typ in a Hilbert space. In par...
