On the hypoellipticity of infinite-dimensional differential operators
N. N. Frolov
Abstract:
An infinite-dimensional differential operator with constant coefficients is considered in the paper. A number of necessary conditions for the hypoellipticity of such an operator are proved. These conditions are also sufficient for the hypoellipticity of finite-dimensional differential operators.
Bibliography: 10 titles.
