Hypoellipticity of a Class of Infinitely Degenerate Second Order Operators and Systems
Lyudmila Korobenko, Cristian Rios · arXiv (Cornell University) · 2013
In this paper we establish a hypoellipticity result for second order linear operators comprised by a linear combination, with infinite vanishing coefficients, of subelliptic operators in separate spaces. This generalizes previous known results.
