    On finite groups with a few number of relative commutativity degrees 

    Type: Conference Paper
    Author : احمد عرفانیان مشیری نژاد; Ahmad Erfanian
    Year: 2013

    On the commutativity degree of compact groups 

    Type: Journal Paper
    Author : رشید رضائی; احمد عرفانیان مشیری نژاد; rashid rezaei; Ahmad Erfanian
    Year: 2009
    Abstract:

    In any finite group G, the commutativity degree of G (denoted

    by d(G)) is the probability that two randomly chosen elements of G commute.

    More generally, for every n ≥ 2 the nth commutativity degree

    (denoted by dn...

    Relative non nil n-graph of finite groups 

    Type: Journal Paper
    Author : احمد عرفانیان مشیری نژاد; بهناز طلوع حقیقی; Ahmad Erfanian; Behnaz Tolue Haghighi
    Year: 2012
    Abstract:

    ABSTRACT: Suppose G is not a nilpotent group of class at most n (a non nil-n group). Consider a subgroup H of G. In

    this paper, we introduce the relative non nil-n graph (n)

    H;G of a finite group G. It is a ...

    Relative n-isoclinism Classes and Relative n-th Nilpotency Degree of Finite Groups 

    Type: Journal Paper
    Author : احمد عرفانیان مشیری نژاد; Rashid Rezaei; Francesco G. Russo; Ahmad Erfanian
    Year: 2013
    Abstract:

    We correlate the notion of n-isoclinismof finite groups, introduced by J. C. Bioch in 1976,with the

    relative n-th nilpotency degree, recently studied in literature. We characterize also all the pairs which are

    isoclinic with (C,D8) via...

    Parents’ Conceptual Involvement in their Children’s Education: An Assessment-oriented View 

    Type: Journal Paper
    Author : رضا پیش قدم; شقایق شایسته صدفیان; Reza Pishghadam; Shaghayegh Shayesteh Sadafian
    Year: 2013
    Abstract:

    long engaged the minds of not only teachers and students but also their parents. Thus, this study sought to delve into parents’ conceptions of assessment with respect to external variables including gender, major, and degree. In doing so, Parents...

    LABORATORIAL INVESTIGATING OF THE SCOURING EXTENSION IN THE RANGE OF TRAPEZOIDAL AND RECTANGULAR MULTIPLE VANES TO DIRECT THE FLOW IN THE RIVERS BENDS 

    Type: Journal Paper
    Author : محسن کرامت زاده; Mahmood Shafai, Bajestan; کاظم اسماعیلی; Mohsen Keramat zade; Kazem Esmaili
    Year: 2014
    Abstract:

    In this study the application of trapezoidal vanes in the rivers bend as the substitute for the rectangular structures to control the erosion in the external bank has been implemented. To reach the research objective, some ...

    On the Exterior Degree of the Wreath Product of Finite Abelian Groups 

    Type: Journal Paper
    Author : احمد عرفانیان مشیری نژاد; FADILA NORMAHIA ABD MANAF; FRANCESCO G. RUSSO; NOR HANIZA SARMIN; Ahmad Erfanian
    Year: 2014
    Abstract:

    Abstract. The exterior degree d ^(G) of a finite group G has been recently introduced by

    Rezaei and Niroomand in order to study the probability that two given elements x and y of G

    commute in the nonabelian exterior square G ^G...
