Topology: continuity on product of (metric) spaces
1
$begingroup$
What are the conditions so that the function defined on the product space $Xtimes Y$ $f: X times Yrightarrow mathbb{Z}$ is continuous. For example, is there a condition that says that if any restriction on $X times{y_0}$ or ${x_0}times Y $ is continuous, then $f$ is continuous? Are there other conditions if we deal with metric spaces ?
