AbstractLet X = (X1, …, Xm) be an infinitely degenerate system of vector fields. We study the existence and regularity of multiple solutions of the Dirichlet problem for a class of semi‐linear infinitely degenerate elliptic operators associated with the sum of square operator δX = ∑j = 1m Xj* Xj (© 2009 WILEY‐VCH Verlag GmbH & Co.
