Abstract
Let be an algebraically closed field. Consider a reductive group over . Let be a projective variety over with a -action and let be a very ample -linearized line bundle on . Suppose that descends to the GIT quotient of by . If satisfies the property one can ask if its descent also has property. In this article, we show this is the case under certain conditions. We then apply our results to some cases of interest. As a consequence of our results, we show that if is a finite group and satisfies property and its descent satisfies property then it satisfies property as well under suitable conditions.
