Recently, Cho et al. [Y. J. Cho, R. Saadati, S. H. Wang, Common xed point theorems on generalized distance in ordered cone metric spaces, Comput. Math. Appl. 61 (2011) 1254-1260] dened the concept of the c-distance in a cone metric space and proved some xed point theorems on c-distance. In this paper, we prove some new xed point and common xed point theorems by using the distance in ordered con...

Backward Error Analysis (BEA) has been a crucial tool when analyzing long-time behavior of numerical integrators, in particular, one is interested in the geometric properties of the perturbed vector field that a numerical integrator generates. In this article we present a new framework for BEA on manifolds. We extend the previously known “exponentially close” estimates from R to smooth manifold...

Monotone bounded distributive lattice expansions (DLMs) are boundeddistributive lattices augmented by nitary operations that are isotone orantitone in each coordinate. Such algebras encompass most algebras withbounded distributive lattice reducts that arise from logic, and general-ize bounded distributive lattices with operators. We de ne the canonicalextension for DLMs and ...

We prove that the property " P doesn't make the old reals Lebesgue null " is preserved under countable support iterations of proper forcings, under the additional assumption that the forcings are nep (a generalization of Suslin proper) in an absolute way. We also give some results for general Suslin ccc ideals. Hypothesis 1: Let (P β , ˜ Q β) β<< be a countable support iteration of proper forci...

motivated by samet et al. [nonlinear anal., 75(4) (2012), 2154-2165], we introduce the notions of $alpha$-$phi$-fuzzy contractive mapping and $beta$-$psi$-fuzzy contractive mapping and prove two theorems which ensure the existence and uniqueness of a fixed point for these two types of mappings. the presented theorems extend, generalize and improve the corresponding results given in the literature.

in this paper we define intuitionistic fuzzy metric and normedspaces. we first consider finite dimensional intuitionistic fuzzy normed spacesand prove several theorems about completeness, compactness and weak convergencein these spaces. in section 3 we define the intuitionistic fuzzy quotientnorm and study completeness and review some fundamental theorems. finally,we consider some properties of...

Abstract Negative dependence of sequences random variables is often an interesting characteristic their distribution, as well a useful tool for studying various asymptotic results, including central limit theorems, Poisson approximations, the rate increase maximum, and more. In study probability models tournaments, negative participants’ outcomes arises naturally, with application to results. p...

In this paper, the case of Jupiter being found in hydrodynamic equilibrium is for first time investigated solely by mathematical methods. With help method, formulas energy balance oval and vortex are found, which summed as permanent kinetic constantly provide stable rotational movements Jupiter. To find total turbulent mode, Green’s function methods with special definitions flow functions that ...

Infertility is a very disastrous side effect in young females, especially in traditional male-dominated societies. The aim of this talk is to discuss the possible ways for fertility preservation in both man and woman. Another aspect is to how to predict women at threat of premature ovarian failure. It will also illustrate the association of cytochrome P450 (CYP2C19) polymorphism with ovarian to...

A set A of vertices of a graph G is called d-scattered in G if no two d-neighborhoods of (distinct) vertices of A intersect. In other words, A is d-scattered if no two distinct vertices of A have distance at most 2d. This notion was isolated in the context of finite model theory by Gurevich and recently it played a prominent role in the study of homomorphism preservation theorems for special cl...
