On Psiconditional asymptotic stability of first order nonlinear matrix Lyapunov system
2
2
We provide necessary and sucient conditions for psiconditional asymptotic stability of the solution of a linear matrix Lyapunov system and sucientconditions for psi conditional asymptotic stability of the solution of a rst ordernonlinear matrix Lyapunov system X0 = A(t)X + XB(t) + F(t;X).

Convergence theorems of implicit iterates with errors for generalized asymptotically quasinonexpansive mappings in Banach spaces
2
2
In this paper, we prove that an implicit iterative process with errors converges strongly to a common xed point for a nite family of generalizedasymptotically quasinonexpansive mappings on unbounded sets in a uniformlyconvex Banach space. Our results unify, improve and generalize the corresponding results of Uddin and Khan [4], Sun [21], Wittman [23], Xu and Ori [26] andmany others.

properties of M−hyoellipticity for pseudo
differential operators
2
2
In this paper we study properties of symbols such that these belong to class of symbols sitting insideSm ρ,φ that we shall introduce as the following. So for because hypoelliptic pseudodifferential operatorsplays a key role in quantum mechanics we will investigate some properties of M−hypoelliptic pseudodifferential operators for which define base on this class of symbols. Also we consider maximal andminimal operators of M−hypoelliptic pseudo differential operators and we express some results aboutthese operators.

On positive solutions for a class of infinite semipositone problems

We discuss the existence of a positive solution to the innite semipositone problemu = au bu f(u) cu ; x 2 ; u = 0; x 2 @;where is the Laplacian operator, > 1, 2 (0; 1), a; b and c are positive constants, is a boundeddomain in RN with smooth boundary @, and f : [0;1) ! R is a continuous function such thatf(u) ! 1 as u ! 1. Also we assume that there exist A > 0 and > 1 such that f(s) As, forall s 0. . We obtain our result via the method of sub and supersolutions.

A modified LLL algorithm for change of ordering of Grobner basis
2
2
In this paper, a modied version of LLL algorithm, which is a an algorithm with outputsensitivecomplexity, is presented to convert a given Grobner basis with respect to a specic order of a polynomialideal I in arbitrary dimensions to a Grobner basis of I with respect to another term order.Also a comparison with the FGLM conversion and Buchberger method is considered.

Sigmaweak amenability of Banach algebras

Let A be a Banach algebra, be continuous homomorphism on A with (A) = A. The boundedlinear map D : A ! A is derivation, ifD(ab) = D(a) (b) + (a) D(b) (a; b 2 A):We say that A is weakly amenable, when for each bounded derivation D : A ! A, there existsa 2 A such that D(a) = (a) a a (a). For a commutative Banach algebra A, we showA is weakly amenable if and only if every derivation from A into a symmetric BanachAbimodule X is zero. Also, we show that a commutative Banach algebra A is weakly amenableif and only if A# is #weakly amenable, where #(a + ) = (a) + .

Fuzzy difference equations of Volterra type
2
2
In this work we introduce the notion of fuzzy volterra dierence equations and study the dynamicalproperties of some classes of this type of equations. We prove some comparison theorems for theseequations in terms of ordinary volterra dierence equations. Using these results the stability of thefuzzy nonlinear volterra dierence equations is investigated.
