On continuous cohomology of locally compact Abelian groups and bilinear maps
(University of Guilan, 2013-11-01)Let $A$ be an abelian topological group and $B$ a trivial topological $A$-module. In this paper we define the second bilinear cohomology with a trivial coefficient. We show that every abelian group can be embedded in a ...

Fully primary modules and some variations
(University of Guilan, 2013-11-01)Let R be a commutative ring and M be an R-module. We say that M is fully primary, if every proper submodule of M is primary. In this paper, we state some characterizations of fully primary modules. We also give some ...

The generalized total graph of modules respect to proper submodules over commutative rings.
(University of Guilan, 2014-06-01)Let $M$ be a module over a commutative ring $R$ and let $N$ be a proper submodule of $M$. The total graph of $M$ over $R$ with respect to $N$, denoted by $T(Gamma_{N}(M))$, have been introduced and studied in [2]. In this ...

Asymptotic behaviour of associated primes of monomial ideals with combinatorial applications
(University of Guilan, 2014-06-01)Let $R$ be a commutative Noetherian ring and $I$ be an ideal of $R$. We say that $I$ satisfies the persistence property if $mathrm{Ass}_R(R/I^k)subseteq mathrm{Ass}_R(R/I^{k+1})$ for all positive integers $kgeq 1$, which ...

Some results on Noetherian semigroup
(University of Guilan, 2014-06-01)In this paper we study some results on Noetherian semigroups. We show that if $S_S$ is an strongly faithful $S$-act and $S$ is a duo weakly Noetherian, then we have the following.

Primal strong co-ideals in semirings
(University of Guilan, 2014-06-01)In this paper, we introduce the notion of primal strong co-ideals and give some results involving them. It is shown thatsubtractive strong co-ideals are intersection of all primal strong co-ideals that contain them. Also ...

Cubic symmetric graphs of orders $36p$ and $36p^{2}$
(University of Guilan, 2014-06-01)A graph is textit{symmetric}, if its automorphism group is transitive on the set of its arcs. In this paper, we classifyall the connected cubic symmetric graphs of order $36p$ and $36p^{2}$, for each prime $p$, of which ...

A note on primary-like submodules of multiplication modules
(University of Guilan, 2014-12-01)Primary-like and weakly primary-like submodules are two new generalizations of primary ideals from rings to modules. In fact, the class of primary-like submodules of a module lie between primary submodules and weakly ...

Triple factorization of non-abelian groups by two maximal subgroups
(University of Guilan, 2014-12-01)The triple factorization of a group $G$ has been studied recently showing that $G=ABA$ for some proper subgroups $A$ and $B$ of $G$, the definition of rank-two geometry and rank-two coset geometry which is closely related ...

Some numerical results on two classes of finite groups
(University of Guilan, 2015-06-01)In this paper, we consider the finitely presented groups $G_{m}$ and $K(s,l)$ as follows;$$G_{m}=langle a,b| a^m=b^m=1,~[a,b]^a=[a,b],~[a,b]^b=[a,b]rangle $$$$K(s,l)=langle a,b|ab^s=b^la,~ba^s=a^lbrangle;$$and find the ...
