اگر خانواده تمام توابعی مانند(f(z که در دایره واحد تحلیلی،تک ارز،0 =(f(z و 1= (f(z را با s نمایش دهیم آنگاه خانواده s دارای خواص و کاربردهای منحصربه فردی می باشد. در این پایان نامه برای شروع ، کرانهایی برای نرم اعضای s و مشتق آنها حاصل شده است . در ادامه با معرفی زیر کلاسهایی از خانواده s مانند توابع ستاره گون ، ستاره گون از مرتبه a ،محدب ، محدب از مرتبه a،ستاره گون قوی ، ستاره گون قوی از مرتب...

among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...

we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...

فرض کنیم $a:[0,infty] ightarrow l(mathbb{c}^n,mathbb{c}^n)$ نگاشت اندازه پذیر لبگی باشد که در شرط $$sup_{sgeq0}int_0^infty |e^{int_s^t [a( au)-2m(a( au)i_n]d au}|dt<infty.$$ صدق کند. نگاشت فنرگون $-a(t)$ مجانبی را در فضای اقلیدسی $mathbb{c}^n$ تعریف می کنیم و به بررسی ارتباط بین این مفهوم و زنجیرهای لاونر می پردازیم. همچنین با تعریف مفهوم نمایش $-a(t)$ پارامتری، نشان می دهیم هرگاه...
