Signature submanifolds for some equivalence problems
M

Z
Pahlevani Tehrani
This article concerned on the study of signature submanifolds for curves under Lie
group actions SE(2), SA(2) and for surfaces under SE(3). Signature submanifold is a regular
submanifold which its coordinate components are dierential invariants of an associated
manifold under Lie group action, and therefore signature submanifold is a key for solving
equivalence problems.

Rajabi Eyvali
In this paper, tripled coincidence points of mappings satisfying -contractive
conditions in the framework of partially ordered Gb-metric spaces are obtained. Our results
extend the results of Aydi et al. [H. Aydi, E. Karapnar and W. Shatanawi, Tripled xed
point results in generalized metric space, J. Applied Math., Volume 2012, Article ID 314279,
10 pages]. Moreover, some examples of the main result are given.

Topological number for locally convex topological spaces with continuous semi-norms
M
Rahimi
S.M
Vaezpour
In this paper we introduce the concept of topological number for locally convex
topological spaces and prove some of its properties. It gives some criterions to study locally
convex topological spaces in a discrete approach.

Solution of the rst order fuzzy dierential equations with generalized dierentiability
L
Jamshidi
T
Allahviranloo
In this paper, we study rst order linear fuzzy dierential equations with fuzzy
coecient and initial value. We use the generalized dierentiability concept and apply the
exponent matrix to present the general form of their solutions. Finally, one example is given
to illustrate our results.

Higher rank numerical ranges of rectangular matrix polynomials
GH
Aghamollaei
M
Zahraei
In this paper, the notion of rankk numerical range of rectangular complex ma-
trix polynomials are introduced. Some algebraic and geometrical properties are investigated.
Moreover, for ϵ > 0; the notion of Birkho-James approximate orthogonality sets for ϵhigher
rank numerical ranges of rectangular matrix polynomials is also introduced and studied. The
proposed denitions yield a natural generalization of the standard higher rank numerical
ranges.

Module amenability and module biprojectivity of θ-Lau product of Banach algebras
D
Ebrahimi Bagha
H
Azaraien
In this paper we study the relation between module amenability of θ - Lau product A×θB and that of Banach algebras A, B. We also discuss module biprojectivity of A×θB. As a consequent we will see that for an inverse semigroup S, l 1 (S) ×θ l 1 (S) is module amenable if and only if S is amenable.
