This paper has studied David Ross`s solutions for ethical mutual competitions. For Ross, the mutual competition happens in ethical duty of the present, and one should give priority to those duties with more emphasized obligation. He has considered special relationship as the foundation for ethical duties upon which the norm for priority and the degree of obligation are based. As is understood b...

abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...

One of the issues that has been considered by the researchers in terms of theory and practice is the problem of finding minimum norm solution. In fact, in general, absolute value equation may have infinitely many solutions. In such cases, the best and most natural choice is the solution with the minimum norm. In this paper, the minimum norm-1 solution of absolute value equation is investigated. ...
