We construct the s-Gauss probability space by introducing the s-Gaussian density function in for , a generalization of the classic Gaussian density function. Based on the s-Gaussian density function, we propose the -Ehrhard symmetrization which is an extension of the traditional Ehrhard symmetrization for sets in . In particular, we establish the s-Gaussian isoperimetric inequality with respect to s-Gaussian measure in . Furthermore, we propose and prove the s-Ehrhard-Borell inequalities for when one of the two sets is a Borel set whilst the other being a convex set as well as the case when two sets are convex in with different methods.
