##### FINITE GROUPS WITH FIVE NON-CENTRAL CONJUGACY CLASSES

*Volume 4, Issue 2 , January 2017, Pages 85-95*

#####
**Abstract **

Let G be a finite group and Z(G) be the center of G. For a subset A of G, we define kG(A), the number of conjugacy classes of G that intersect A non-trivially. In this paper, we verify the structure of all finite groups G which satisfy the property ...

##### FUZZY OBSTINATE IDEALS IN MV-ALGEBRAS

*Volume 4, Issue 2 , January 2017, Pages 97-101*

#####
**Abstract **

In this paper, we introduce the notion of fuzzy obstinate ideals in MV -algebras. Some properties of fuzzy obstinateideals are given. Not only we give some characterizations of fuzzy obstinate ideals, but also bring the extension theorem of fuzzy obstinate ideal of an MV -algebra A. We investigate ...

##### RADICAL OF FILTERS IN RESIDUATED LATTICES

*Volume 4, Issue 2 , January 2017, Pages 111-121*

#####
**Abstract **

In this paper, the notion of the radical of a filter in residuated lattices is defined and several characterizations of the radical of a filter are given. We show that if F is a positive implicative filter (or obstinate filter), then ...

##### REES SHORT EXACT SEQUENCES OF S-POSETS

*Volume 4, Issue 2 , January 2017, Pages 123-134*

#####
**Abstract **

In this paper the notion of Rees short exact sequence for S-posets is introduced, and we investigate the conditions for which these sequences are left or right split. Unlike the case for S-acts, being right split does not imply left split. Furthermore, we present equivalent conditions of a right S-poset ...

##### MORE ON EDGE HYPER WIENER INDEX OF GRAPHS

*Volume 4, Issue 2 , January 2017, Pages 135-153*

#####
**Abstract **

Let G=(V(G),E(G)) be a simple connected graph with vertex set V(G) and edge set E(G). The (first) edge-hyper Wiener index of the graph G is defined as: $$WW_{e}(G)=\sum_{\{f,g\}\subseteq E(G)}(d_{e}(f,g|G)+d_{e}^{2}(f,g|G))=\frac{1}{2}\sum_{f\in E(G)}(d_{e}(f|G)+d^{2}_{e}(f|G)),$$ ...
