Let p(x,y) be a positive polynomial of degree n ,p(x,y)=0 only at the origin.Is it possible that

the quotient p(x,y)/[absolute value(x)+absval(y)]^n will have a positive lower bound in the punctured rectangle [-1,1]x[-1,1]-{(0,0)}?

Hey hedi.

Can you explain what you mean symbolically (i.e. mathematically with symbols)?
