May 18	comment	what is the diffrence between a term , constant and variable in first order logic languages ? i will :) i use enderton's text . i will search for those online free texts :) thanx professor
May 18	comment	what is the diffrence between a term , constant and variable in first order logic languages ? @PeterSmith , u r right but if you live in a village in egypt then the idea of getting one or two books to ckeck the definition is not practical! because this may require a long time to get this text !

May 18	accepted	prove that , $2+2+2+2+2+ \cdots= 1+1+1+1+1+\cdots$
May 16	comment	Under what conditions is a zero divisor element $a$ in commutative ring $R$ nilpotent? @HagenvonEitzen , didn't understand your point !
May 16	comment	Under what conditions is a zero divisor element $a$ in commutative ring $R$ nilpotent? @QiaochuYuan , nope , i meant conditions on the element itself !
May 16	comment	Characterizing units in polynomial rings $R[X]$ @JasonDeVito , so how can we complete the proof now ?!
May 15	comment	Characterizing units in polynomial rings $R[X]$ @HagenvonEitzen what do u mean ?
May 15	comment	Under what conditions is a zero divisor element $a$ in commutative ring $R$ nilpotent? math.stackexchange.com/questions/19132/… see this link , there is a comment in the second answer which deduce that an element is nilpotent from being zero divisor ! but i don't understand why this is true !

May 15	comment	Characterizing units in polynomial rings $R[X]$ @JasonDeVito , why $a_n b_m=0$ implies that $a_n$ is nilpotent ? can you explain this more plz ?
May 15	accepted	Group theory between mathematicians and physicists?
May 15	asked	How should we study maths?

May 8	asked	What is the needed background to study tensors?
May 8	awarded	Caucus
May 3	comment	prove that $a_0$ is a unit and that $a_1 , a_2 , .. a_{n}$ are nilpotents in $R$ . it's not necessary that there is an inverse to $p_{n}$ !
May 3	comment	Under what conditions does a ring R have the property that every zero divisor is a nilpotent element? thanx , i think that i will come back to this question when i study these concepts in the future !
