题目：Resistance estimates and Dirichlet forms on some classes of non-p.c.f. fractals
摘要：The resistance estimate of network approximation is an important tool to study analytic properties of fractals such as Laplacians, spectral dimensions, walk dimensions. I will talk about the resistance growth rates on two new classes of fractals; they are constructed by dividing a unit triangle into sub-triangles, then removing some of them in a symmetric pattern. One class we call it triangular carpets is analogous to the Sierpinski carpet. The other class we call it triangular diamonds is graph directed finitely ramified, and is a generalization of the diamond fractal. After verifying the resistance growth rates, we use them to derive a uniform Harnack inequality on the approximation networks. Then apply them to study the $\Gamma$-convergence of the associated Besov spaces to obtain the existence of a local regular Dirichlet form on the fractals, a recent approach to obtain a Laplacian initiated by Grigor'yan and Yang.
