摘要:
Let G be a 2-step nilpotent lie Group of type (H) such that there is a subalgebra of the Lie algebra g which is maximal subordinate for all nontrivial linear functionals on the center g2of the Lie algebra g— Suppose that L is a left invariant operator on G such tha the term or highest homogeneous degree is elliptic in the generating directions on G. Then L is hypoelliptic ⇔ the elements l ∈ (g2)*C for which пl(L*L) is not invertible move away from g*faster than any multiple of log ∣l∣. The implication ⇐ holds for all Lie groups of type (H) ⇔
