Topology Seminar

ROOM: Ayres Hall 316
SPEAKER: Anastasiia Tsvietkova
TITLE: Cat(0) spaces III
POST DOC Talk
TIME: 3:35 p.m.
ROOM: 214 Ayres
SPEAKER: Sergey Melikhov
TITLE: “Configuration spaces in link theory”
ABSTRACT: Abstract: Given a manifold or some other space $X$, there is the question whether it embeds in a given Euclidean space $R^m$, and if so, then in how many inequivalent ways. This includes the problem of classification of knots and links. An idea going back to Gauss is that this must look like an algebraic topology problem to a finite set of points or tangenvectors running over $X$. This configuration space approach turns out to be very powerful, indeed no situations are presently known where it is insufficient. I will review some classical and recent results, constructions and conjectures along these lines.

POST DOC Talk
TIME: 3:35 p.m.
ROOM: 214 Ayres
SPEAKER: Tamer Oraby
TITLE: “Spectra of Large Random Block-Matrices”
ABSTRACT: Random matrix theory has attracted many researchers in diverse areas
of science, such as nuclear & quantum physics, statistics, number theory,
biology, wireless communication, and financial market analysis. In particular,
they study the asymptotic behavior of the eigenvalues of different kinds of
random matrices. Random block- matrices which have deterministic block structure
with blocks that are random matrices arise in some problems of physics and
engineering. In my talk, I am going to present some results about the limit
of the empirical distribution of the eigenvalues of random block-matrices.
