題目: Geometry and Analysis of Dirichlet forms

摘要:
First, for a given regular strongly local Dirichlet form $/mathscr E$ ,under the assumptions of the lower bound ofBakry-Emery's Ricci curvature,local doubling and local Poincare, we obtain the coincidence of the intrinsicdifferentialand distance structures induced by $/mathscr E$.
Second, for the Dirichlet form $E_A$ generated by the operator $div (A/nabla)$,we establish some critical relationsbetween the diffusion matrix $A$, and the coincidence of the intrinsic differential and distance structures induced by $E_A$.
Finally, we also discuss some applications.
