We provide necessary and sucient conditions for psi-conditional as-<br />ymptotic stability of the solution of a linear matrix Lyapunov system and sucient<br />conditions for psi -conditional asymptotic stability of the solution of a rst order<br />non-linear matrix Lyapunov system X0 = A(t)X + XB(t) + F(t;X).

Convergence theorems of implicit iterates with errors for generalized asymptotically quasi-nonexpansive mappings in Banach spaces
G. S.
Saluja
In this paper, we prove that an implicit iterative process with er-<br />rors converges strongly to a common xed point for a nite family of generalized<br />asymptotically quasi-nonexpansive mappings on unbounded sets in a uniformly<br />convex Banach space. Our results unify, improve and generalize the correspond-<br />ing results of Ud-din and Khan [4], Sun [21], Wittman [23], Xu and Ori [26] and<br />many others.

differential operators

Kalleji
In this paper we study properties of symbols such that these belong to class of symbols sitting inside<br />Sm ρ,φ that we shall introduce as the following. So for because hypoelliptic pseudodifferential operators<br />plays a key role in quantum mechanics we will investigate some properties of M−hypoelliptic pseudo<br />differential operators for which define base on this class of symbols. Also we consider maximal and<br />minimal operators of M−hypoelliptic pseudo differential operators and we express some results about<br />these operators.

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

In this paper, a modied version of LLL algorithm, which is a an algorithm with output-sensitive<br />complexity, is presented to convert a given Grobner basis with respect to a specic order of a polynomial<br />ideal I in arbitrary dimensions to a Grobner basis of I with respect to another term order.<br />Also a comparison with the FGLM conversion and Buchberger method is considered.

Sigma-weak amenability of Banach algebras
T.

Mozzami Zadeh
Let A be a Banach algebra, be continuous homomorphism on A with (A) = A. The bounded<br />linear map D : A ! A is derivation, if<br />D(ab) = D(a) (b) + (a) D(b) (a; b 2 A):<br />We say that A is -weakly amenable, when for each bounded derivation D : A ! A, there exists<br />a 2 A such that D(a) = (a) a a (a). For a commutative Banach algebra A, we show<br />A is weakly amenable if and only if every derivation from A into a symmetric Banach<br />Abimodule X is zero. Also, we show that a commutative Banach algebra A is weakly amenable<br />if and only if A# is #weakly amenable, where #(a + ) = (a) + .

Fuzzy difference equations of Volterra type
R.
Memarbashi
A.
Ghasemabadi
In this work we introduce the notion of fuzzy volterra dierence equations and study the dynamical<br />properties of some classes of this type of equations. We prove some comparison theorems for these<br />equations in terms of ordinary volterra dierence equations. Using these results the stability of the<br />fuzzy nonlinear volterra dierence equations is investigated.
