Considering the set of real numbers R, for each x ? A, B(x)={(x??,x+?):?>0}, and x? R\A, let B(x)={[x,x+?):?>0}, unique topology generated by {B(x): R} is denoted ?(A) ( R , ) called an H-space. In this paper, we give some results about these spaces product two them, including separation axioms, wD property, various types compactness connectedness, weaker properties normality.
