Some difference results on Hayman conjecture and uniqueness
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)In this paper, we show that for any finite order entire function $f(z)$, the function of the form $f(z)^{n}[f(z+c)-f(z)]^{s}$ has no nonzero finite Picard exceptional value for all nonnegative integers $n, ...

Iterative methods for finding nearest common fixed points of a countable family of quasi-Lipschitzian mappings
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)We prove a strong convergence result for a sequence generated by Halpern's type iteration for approximating a common fixed point of a countable family of quasi-Lipschitzian mappings in a real Hilbert space. ...

MRA parseval frame multiwavelets in L^2(R^d)
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)In this paper, we characterize multiresolution analysis(MRA) Parseval frame multiwavelets in L^2(R^d) with matrix dilations of the form (D f )(x) = sqrt{2}f (Ax), where A is an arbitrary expanding dtimes d matrix with ...

Smarandache algebras and their subgroups
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)In this paper we define S algebras and show that every finite group can be found in some S algebra. We define and study the S degree of a finite group and determine the S degree of several classes of ...

Uniqueness of meromorphic functions dealing with multiple values in an angular domain
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)This paper uses the Tsuji's characteristic to investigate the uniqueness of transcen- dental meromorphic function with shared values in an angular domain dealing with the multiple values which improve a result ...

A common fixed point theorem on ordered metric spaces
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)A common fixed point result for weakly increasing mappings satisfying generalized contractive type of Zhang in ordered metric spaces are derived.

A generalization of the probability that the commutator of two group elements is equal to a given element
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)The probability that the commutator of two group elements is equal to a given element has been introduced in literature few years ago. Several authors have investigated this notion with methods of the representation theory ...

Para-Kahler tangent bundles of constant para-holomorphic sectional curvature
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)We characterize the natural diagonal almost product (locally product) structures on the tangent bundle of a Riemannian manifold. We obtain the conditions under which the tangent bundle endowed with the determined structure ...

Fully idempotent and coidempotent modules
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)In this paper, the notion of fully idempotent modules is defined and it is shown that this notion inherits most of the essential properties of the usual notion of von Neumann's regular rings. Furthermore, we introduce the ...

Uniserial modules of generalized power series
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)Let R be a ring, M a right R-module and (S,≤) a strictly ordered monoid. In this paper we will show that if (S,≤) is a strictly ordered monoid satisfying the condition that 0 ≤ s for all s ∈ S, then the module [[MS,≤]] ...

An automaton group: a computational case study
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)We introduce a two generated weakly branch contracting automaton group $G$ which is generated by a two state automaton on a three letter alphabet. Using its branch structure and the finiteness nature of ...

Newton-Product integration for a Two-phase Stefan problem with Kinetics
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)We reduce the two phase Stefan problem with kinetic to a system of nonlinear Volterra integral equations of second kind and apply Newton's method to linearize it. We found product integration solution ...

Entropy operator for continuous dynamical systems of finite topological entropy
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)In this paper we introduce the concept of entropy operator for continuous systems of finite topological entropy. It is shown that it generates the Kolmogorov entropy as a special case. If $phi$ is invertible then the entropy ...

Multiple point of self-transverse immesions of certain manifolds
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)In this paper we will determine the multiple point manifolds of certain self-transverse immersions in Euclidean spaces. Following the triple points, these immersions have a double point self-intersection ...

On generalized left (alpha, beta)-derivations in rings
(Springer and the Iranian Mathematical Society (IMS), 2012-12-01)Let $R$ be a 2-torsion free ring and $U$ be a square closed Lie ideal of $R$. Suppose that $alpha, beta$ are automorphisms of $R$. An additive mapping $delta: R longrightarrow R$ is said to be a Jordan left $(alpha,beta) ...
