  • COSPECTRALITY MEASURES OF GRAPHS WITH AT MOST SIX VERTICES 

    Abdollahi, A.؛ Janbaz, Sh.؛ Oboudi, M.R. (Yazd University, 2014-02-01)
    Cospectrality of two graphs measures the differences between the ordered spectrum of these graphs in various ways. Actually, the origin of this concept came back to Richard Brualdi's problems that are proposed in cite{braldi}: ...

  • HYPERTRANSCENDENTAL FORMAL POWER SERIES OVER FIELDS OF POSITIVE CHARACTERISTIC 

    Sharif, Habib (Yazd University, 2014-02-01)
    Let $K$ be a field of characteristic$p>0$, $K[[x]]$, the ring of formal power series over $ K$,0$, $K[[x]]$, the ring of formal power series over $ K$,$K((x))$, the quotient field of $ K[[x]]$, and $ K(x)$ the fieldof rational functions over $K$. We shall give ...

  • STABILIZER TOPOLOGY OF HOOPS 

    Borzooei, R.A.؛ Aaly Kologani, M. (Yazd University, 2014-02-01)
    In this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them.  And we try to find that how they can be equal and investigate that under ...

  • AUTOMORPHISM GROUP OF GROUPS OF ORDER pqr 

    Ghorbani, M.؛ Nowroozi Larki, F. (Yazd University, 2014-02-01)
    H"{o}lder in 1893 characterized all groups of order $pqr$ where  $p>q>r$ are prime numbers. In this paper,  by using new presentations of these groups, we compute their full automorphism group.

  • ENLARGED FUNDAMENTALLY VERY THIN Hv-STRUCTURES 

    Vougiouklis, T. (Yazd University, 2014-02-01)
    We study a new class of $H_v$-structures called Fundamentally Very Thin. This is an extension of the well known class of the Very Thin hyperstructures. We present applications of these hyperstructures.

  • THE ORDER GRAPHS OF GROUPS 

    Payrovi, SH.؛ Pasebani, H. (Yazd University, 2014-02-01)
    Let $G$ be a group. The order graph of $G$ is the (undirected)graph $Gamma(G)$,those whose vertices are non-trivial subgroups of $G$ and two distinctvertices $H$ and $K$ are adjacent if and only if either
