برای هر راس u وv از گرافg ، مجموعه یi[u, v] شامل تمام راس هایی است که در مسیرهای ژئودتیک u-v از گراف g قرار دارد. اگرs زیر مجموعه ای از راس های گراف g باشد، آنگاه i[s] اجتماع تمام مجموعه های i[u, v] برای u,v? s است. مجموعه یs? v(g) یک مجموعه ی ژئودتیک است اگر i[s]= v(g) .به کوچکترین اندازه ی مجموعه های ژئودتیک در گرافg عدد ژئودتیک گویند و با g(g) نشان می دهند. مجموعه ی...
it is shown that every almost linear bijection $h : arightarrow b$ of a unital $c^*$-algebra $a$ onto a unital$c^*$-algebra $b$ is a $c^*$-algebra isomorphism when $h(3^n u y) = h(3^n u) h(y)$ for allunitaries $u in a$, all $y in a$, and all $nin mathbb z$, andthat almost linear continuous bijection $h : a rightarrow b$ of aunital $c^*$-algebra $a$ of real rank zero onto a unital$c^*$-algebra...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
بین این سه، چیزی _ ای میان مفهوم دامنه تجزیه یکتا، قضیه کرول-اشمیت و قضیه ژوردان-هلدر وجود دارد. رابطه _ رابطه جایی آزاد وجود دارد. قضیه کرول-اشمیت _ گوییم که در همه این سه موضوع یک تکواره جابه _ است که ما به طور معادل می را ar ∈ c رده یکریختی مدول ⟨ar⟩ و r های راست از طول متناهی روی حلقه _ مدول - r رده همه c گوید که اگر _ می یک تکواره v (c) = {⟨ar⟩ | ar ∈ c} در این صورت ،ar های یکریخت با _ ...
this experiment was designed to characterize the effects of size and concentration of an iranian clinoptilolite zeolite on the growth officus benjamina (starlight) in peat base media. ficus benjamina was stock rooted and grown in a peat consisting perlite (2: 1 v/v) (p: pe), zeolite (10, 20, 30 and 40 v/v %, two sizes 0.5-3 mm and 3-8 mm) instead of peat in p: pe (2: 1 v/v) media. ficus benjami...
It is shown that every almost linear bijection $h : Arightarrow B$ of a unital $C^*$-algebra $A$ onto a unital$C^*$-algebra $B$ is a $C^*$-algebra isomorphism when $h(3^n u y) = h(3^n u) h(y)$ for allunitaries $u in A$, all $y in A$, and all $nin mathbb Z$, andthat almost linear continuous bijection $h : A rightarrow B$ of aunital $C^*$-algebra $A$ of real rank zero onto a unital$C^*$-algebra...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
the electrocatalysis of the oxygen reduction reaction (orr) on carbon supportedpt-v (1:1) catalyst in polymer electrolyte fuel cells (pefc) was investigated. atan oxygen pressure of one atm an enhanced electrocatalytic property of pt-v/ccompared with pt/c is revealed. these results indicate the occurrence of adifferent electrocatalytic mechanism for the orr on pt/c and pt-v/c. anincrease of mas...
