Title: On dense totipotent free subgroups in full groups

Abstract: I will present the following notions and results. The perfect kernel of a countable group Gamma is the largest closed subspace of the space of subgroups of Gamma without isolated points. We introduce the class of totipotent ergodic probability measure preserving (p.m.p.) actions of Gamma: those for which almost every point-stabilizer has dense conjugacy class in the perfect kernel. Equivalently, the support of the associated Invariant Random Subgroup (IRS) coinicdes with the whole perfect kernel (it is as large as possible). We prove that every ergodic p.m.p. equivalence relation R of cost


Numerical Analysis Seminar

Location: ZOOM

Speaker: Ronald DeVore, Texas A&M

Title: Deep Learning and Neural Networks: The Mathematical View

Abstract: Deep Learning is much publicized and has had great empirical success on challenging problems in learning. Yet there is no quantifiable proof of performance and certified guarantees for these methods. This talk will give an overview of Deep Learning from the viewpoint of mathematics and numerical computation.
