Some results on space-like self-shrinkers

We study space-like self-shrinkers of dimension $n$ in pseudo-Euclidean space $\text{ir}{m+n}_m$with index $m$. We derive drift Laplacian of the basic geometric quantities and obtain their volume estimates in pseudo-distance function. Finally, we prove a rigidity results under minor growth conditions interms of the mean curvature or the image of Gauss maps.
