WebTheorems 1.1 and 1.2 show us that intersection with a random high dimensional subspace enjoys strong concentration of measure. In the proof of theorem 1.1, we see that decreasing the dimension can cause a decrease in the concentration phe-nomenon. The next result deals with the case that the dimension of the random subspace is small. faulkner subaru service mechanicsburg https://matthewdscott.com
