##### 76. A note on unique solvability of the absolute value equation

*Volume 02, Issue 02 , Spring 2013, , Pages 77-81*

#####
**Abstract **

It is proved that applying sufficient regularity conditions to the interval matrix $[A-|B|,A + |B|]$, we can create a new unique solvability condition for the absolute value equation $Ax + B|x|=b$, since regularity of interval matrices implies unique solvability of their corresponding absolute ...

*Volume 03, Issue 02 , Spring 2014, , Pages 79-85*

#####
**Abstract **

For two normal edge-transitive Cayley graphs on groups H and K which have no common direct factor and $\gcd(|H/H^\prime|,|Z(K)|)=1=\gcd(|K/K^\prime|,|Z(H)|)$, we consider four standard products of them and it is proved that only tensor product of factors can be normal edge-transitive.

##### 84. A generalization of Bertrand's test

*Volume 02, Issue 03 , Summer 2013, , Pages 145-151*

#####
**Abstract **

One of the most practical routine tests for convergence of a positive series makes use of the ratio test. If this test fails, we can use Rabbe's test. When Rabbe's test fails the next sharper criteria which may sometimes be used is the Bertrand's test. If this test fails, we can use a generalization ...
