In this paper, we propose a modified implicit iteration for two finite families of asymptotically pseudocontractive mappings. Further, convergence theorems for approximation of common fixed points of two finite families of uniformly Lipschitzian asymptotically pseudocontractive mappings are proved in Banach spaces. Our results extend and improve a number of results in the literature. We also re...

It is well known that high gain observers exist for single output nonlinear systems that are uniformly observable and globally Lipschitzian. Under the same conditions, we show that these systems admit semi-global and finite-time converging observers. This is achieved with a derivation of a new sufficient condition for local finite-time stability, in conjunction with applications of geometric ho...

Let $X$ be a reflexive Banach space, $T:Xto X$ be a nonexpansive mapping with $C=Fix(T)neqemptyset$ and $F:Xto X$ be $delta$-strongly accretive and $lambda$- strictly pseudocotractive with $delta+lambda>1$. In this paper, we present modified hybrid steepest-descent methods, involving sequential errors and functional errors with functions admitting a center, which generate convergent sequences ...

Let L : C∞(M ;E)→ C∞(M ;E) be a second order, uniformly elliptic, semipositive-definite differential operator on a complete Riemannian manifold of bounded geometry M , acting between sections of a vector bundle with bounded geometry E over M . We assume that the coefficients of L are uniformly bounded. Using finite speed of propagation for L, we investigate properties of operators of the form f...

Then we...

In this paper, the results of a quadruple coincidence point (QCP) are established for commuting mapping in setting fuzzy metric spaces (FMSs) without using partially ordered set. addition, several related presented order to generalize some prior findings area. Finally, support and enhance our theoretical ideas, non-trivial examples applications finding unique solution Lipschitzian integral syst...

Abstract: Many hypersurfaces ω in R can be viewed as a subset of the boundary Γ of an open subset Ω of R . In such cases, the gradient and Hessian matrix of the associated oriented distance function bΩ to the underlying set Ω completely describe the normal and the N fundamental forms of ω, and a fairly complete intrinsic theory of Sobolev spaces on C-hypersurfaces is available in Delfour (2000)...
