We consider the quotient of the Hilbert space...by the set of measure preserving maps on... This is nothing but the set of Borel measures of finite second moments on... We study a partial trace of the hessian on a subset of functions defined on the quotient space and verify a distinctive smoothing effect of the "heat flows" they generate for a particular class of initial conditions. To this end, we develop a theory of Fourier analysis and conic surfaces and identify a measure which allows for an integration by parts. (This is a joint work with Y.T. Chow). - see full abstract at event URL.
