In this paper we introduce the concept of α-commutator which its definition is based on generalized conjugate classes. With this notion, α-nilpotent groups, α-solvable groups, nilpotency and solvability of groups related to the automorphism are defined. N(G) and S(G) are the set of all nilpotency classes and the set of all solvability classes for the group G with respect to different automorphi...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

in this paper, we introduce and study the notion of precompacttopological generalized groups and some new results are given.
the author studies the $bf r$$g$-module $a$ such that $bf r$ is an associative ring, a group $g$ has infinite section $p$-rank (or infinite 0-rank), $c_{g}(a)=1$, and for every proper subgroup $h$ of infinite section $p$-rank (or infinite 0-rank respectively) the quotient module $a/c_{a}(h)$ is a finite $bf r$-module. it is proved that if the group $g$ under consideration is local...
فایتوپلاسماها به عنوان یکی از مهم ترین عوامل ایجادکننده بیماری در روی گیاهان، خسارات فراوانی به انگور در سراسر جهان وارد می کنند. طی سال های اخیر در مناطق مرکزی ایران علائم پیچیدگی، زردی و ارغوانی شدن برگ درختان مو مشاهده شد که با علائم بیماری های فایتوپلاسمایی شباهت داشت. به منظور شناسایی و گروه بندی فایتوپلاسماهای آلوده کننده انگور منطقه مرکزی ایران، نمونه هایی با علائم فایتوپلاسمایی جمع آوری...
