G. G. Kazaryan, V. N. Markaryan Erevan State Pedagogical Institute
Abstract:
Lower bounds are established for the functional dimension of the solution space of hypoelliptic operators with constant coefficients. As a corollary of these estimates a criterion is found for the ellipticity of a differential operator in terms of the functional dimension.
