给出了非紧流形上一类次椭圆算子的超/弱Poincaré不等式成立的充分条件。作为应用,刻划了ℝ-2上的Gruschin型算子和Heisenberg群上的Kohn-Laplacian算子的伴随马氏半群的本质谱和收敛速度。
Sufficient conditions are presented for super/weak Poincaré inequalities to hold for a class of hypoelliptic operators on noncompact manifolds. As applications, the essential spectrum and the convergence rate of the associated Markov semigroup are described for Gruschin type operators on ℝ2 and Kohn-Laplacian type operators on the Heisenberg group.
