英文摘要 | Let (E, F, mu) be a probability space, a (not necessarily symmetric) Dirichlet form on L-2(mu), and P-t the associated sub-Markov semigroup. The equivalence of the following eight properties is studied (i) the L-2-uniform integrability of the unit ball in the Sobolev space; (ii) the super-Poincare inequality (1.2); (iii) the F-Sobolev inequality (1.3); (iv) the L2-uniform integrability of P-t; (v) the L-2-uniform integrability of the associated resolvents; (vi) the compactness of P-t; (vii) the compactness of the associated resolvents; (viii) empty essential spectrum of the associated generator. The main results can be summarized as follows. In general, (i), (ii) and (iii) are equivalent to each other, and they imply (iv) which is equivalent to (v). If P-t has transition density and, F is mu-separable, then the first seven properties from (i) to (vii) are equivalent. If in addition (E, D(E)) is symmetric, then all the above eight properties are equivalent. Moreover, the essential spectrum of the generator is estimated by using weaker functional inequalities. |
