摘要：
For a family of infinite-dimensional diffusions with degenerate noise, we develop a modified Gamma calculus on finite-dimensional projections of the equation in order to produce explicit functional inequalities that can be scaled to infinite dimensions. The choice of our Gamma operator appears canonical in our context, as the estimates depend only on the induced control distance. We apply the general analysis to a number of examples, ex
