chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...

نگاشت های گویای استثنایی آن دسته از نگاشت های گویا هستند که نقطه ی تناوبی از هر دوره ی تناوب دلخواه نداشته باشند. ثابت شده است اگر نگاشت گویای r از درجه ی d ، نقطه ی تناوبی از دوره ی تناوب اولیه ی n نداشته باشد آن گاه {(d,n) ? { (2,2), (2,3), (3,2), (4,2) نگاشت های گویای استثنایی تحت تزویج های همدیس دسته بندی و مشخص شده اند. به عنوان مثال هر نگاشت گویای درجه ی 2 که فاقد مداری از دوره ی تن...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...

هدف از این پایان نامه بررسی دگرگونش نظریه های پیمانه ای یانگ - میلز است . دگرگونش قسمت پیمانه ای نظیر سلام - واینبرگ - گلاشو را به تفصیل مورد بررسی قرار خواهیم داد. چنانکه در مقدمه نیز ذکر شد معادلات حرکت برای لاگرانژی آبلی را قبلا بدست آورده اند، معادلات حرکت برای لاگرانژی غیرآبلی را نیز می یابیم. سپس لاگرانژی پیمانه ای دگرگوینده کل (آبلی + غیرآبلی) را در نظر می گیریم و آن را برحسب میدانهای ذر...

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...
