    Let $X,Y$ be a pair of spaces with continuous actions of a topological group $G$. Form the $G$-space $Xtimes Y$ with the diagonal action, and let $Xtimes_GY$ be the quotient $(Xtimes Y)/G$. In particular, if $X$ is a right $G$-space and $Y$ is a left $G$-space, then $Xtimes_GY=Xtimes Y/[(xg,y)sim (x,gy)]$. The space $Xtimes_GY$ is often called the Borel Construction, or Balance Product.
