โฆ Synopsis
Given a Gaussian distribution G in l 2 we construct l 2 -valued i.i.d. random variables X 1 ; X 2 ; : : : such that:
absolutely continuous with respect to G, and the total variation |F n -G| 9 0. This contrasts to Prokhorov's (Dokl. Akad. Nauk SSSR (N.S) 83 (1952) 797) local limit theorem in R k .

In this paper, a straightforward extension of the classical local limit theorem is given. In particular, necessary and sufficient conditions for local limit theorem are presented in terms of function of smoothness.
Multivariate variational inequalities are obtained in terms of the w-functions and the trace of a Fisher-type information matrix. In consequence of these inequalities, the multivariate central limit theorem arises in the sense of the total variation.
