Etemad
This paper continues the investigation of the rst author begun in part one. The hereditary properties of nhomomorphism amenability for Banach algebras are investigated and the relations between nhomomorphism amenability of a Banach algebra and its ide als are found. Analogous to the character amenability, it is shown that the tensor product of two unital Banach algebras is nhomomorphism amenable if and only if each one is n homomorphism amenable.

Operatorvalued bases on Hilbert spaces
M. S.
Asgari
In this paper we develop a natural generalization of Schauder basis theory, we term
operatorvalued basis or simply ovbasis theory, using operatoralgebraic methods. We prove
several results for ovbasis concerning duality, orthogonality, biorthogonality and minimality.
We prove that the operators of a dual ovbasis are continuous. We also dene the concepts of
Bessel, Hilbert ovbasis and obtain some characterizations of them. We study orthonormal
and Riesz ovbases for Hilbert spaces. Finally we consider the stability of ovbases under
small perturbations. We generalize a result of PaleyWiener [4] to the situation of ovbasis.

In this paper, applying the concept of generalized Avalued norm on a right H

module and also the notion of ϕhomomorphism of Finsler modules over C
algebras we rst
improve the denition of the Finsler module over H
algebra and then dene ϕmorphism
of Finsler modules over H
algebras. Finally we present some results concerning these new
ones.

In this paper, we present the numerical solution of ordinary dierential equations
(or SDEs), from each order especially secondorder with timevarying and Gaussian random
coecients. We indicate a complete analysis for secondorder equations in special case of
scalar linear secondorder equations (damped harmonic oscillators with additive or multi
plicative noises). Making stochastic dierential equations system from this equation, it could
be approximated or solved numerically by dierent numerical methods. In the case of linear
stochastic dierential equations system by Computing fundamental matrix of this system, it
could be calculated based on the exact solution of this system. Finally, this stochastic equa
tion is solved by numerically method like EulerMaruyama and Milstein. Also its Asymptotic
stability and statistical concepts like expectation and variance of solutions are discussed.
