Self-adjointness of elliptic operators in infinitely many variables
The results in this paper refer to the existence of second order self- adjoint elliptic operators with variable coefficients in a space of functions with infinite number of variables. One assumes the coefficients are cylindrical and one reduces the stated problem to an analogous one, but for operators with a finite number of variables.
