Title: Coordinate Methods for Solving Eigenvalue Problems in High Dimensions
Abstract: The leading eigenvalue problem of a differential operator
arises in many scientific and engineering applications, in particular
quantum many-body problems. Due to the curse of dimensionality,
conventional algorithms become impractical due to the huge computational
and memory complexity. In this talk, we will discuss some of our recent
works on developing efficient coordinate based approaches for eigenvalue
problems in high dimension and on convergence analysis of randomized
coordinate algorithms based on the theory of random dynamical systems.
