Title: Discrete Approximation on Metric Measure
Spaces of Controlled Geometry via Graphs:
Dirichlet Forms and Harmonic Functions
Abstract:
Based on the approximation of a metric measure space via discrete graphs, we construct
a Dirichlet form. This Dirichlet form is comparable to the upper gradient energy and can
be realized as a -limit of a sequence of induced bilinear forms projected from the discrete
energy form on the approximating graphs. Moreover, we approximate harmonic functions
on a bounded domain with a prescribed Newton-Sobolev boundary data. Based on joint
work with A. Butaev and N. Shanmugalingam.

Eigenvalues/vectors of tensors are a modern concept extending those of matrices. They appear in various non-linear contexts, such as spin glasses, general relativity, artificial intelligence, quantum information theory, string theory, and so on, while the matrix counterpart in linear-contexts. Understanding universal properties across various tensor eigen problems is important, since this assures their wide applicability. I talk about our recent finding of a universality of tensor eigenvalue/vector distributions, which has been achieved by systematically computing them using quantum field theoretical techniques.
