DE/APPLIED AND COMPUTATIONAL MATH SEMINAR
TIME: 3:35-4:30 p.m.
ROOM: Ayres Hall 309A
SPEAKER: Dr. Petr Plechac
TITLE: Statistical closure and reduced Hamiltonian dynamics
Tuesday, September 11
Junior Colloquium
TIME: 3:30 p.m.
ROOM: Ayres Hall 214
SPEAKER: Dr. Remus Nicoara
TITLE: Google’s Secret
Abstract: Everybody knows that Google Inc.'s innovations in search technology made it the No. 1 search engine in the world. Google has recently made public their US patent, which reveals a great deal of how they search and rank web sites. We unveil some of the mathematics behind Google's success: graphs, matrices, eigenvalues and eigenvectors, and deep results such as the Perron-Frobenius theorem.
(Dr. Remus Nicoara grew up in Romania, where he was a top performer in their very prestigious National Mathematical Olympiad, winning each of the First and Second Prizes twice! He did his undergraduate work at the University of Bucharest, Romania, and his graduate work at UCLA. After three years at Vanderbilt, he joins the Mathematics Department here at UT this semester.)
As usual, pizza will be served at 3:30.
Wednesday, September 12
Analysis Seminar
TIME: 3:40 p.m. 4:25 p.m.
ROOM: Ayres Hall 209A
SPEAKER: Dr. Carl Sundberg (joint work with Dr. Stefan Richter)
TITLE: Model theory for commuting tuples of operators, I
Thursday, September 13
COLLOQUIUM
TIME: 3:40 p.m.
ROOM: Ayres Hall 214
SPEAKER: Dr. Gerard Venema, Calvin College, Michigan
TITLE: Representing homology classes of 4-dimensional manifolds
ABSTRACT: The basic problem addressed is which 2-dimenisonal homology classes of simply connected 4-manifolds can be represented by embedded spheres. I will describe both positive and negative results and explore some of the unknown territory between the two.
(Note: Dr. Venema was chosen as a speaker by the Mathematics Graduate Students, and he said I could relay this promise: "I will do my best to give a talk that is both substantive and accessible to the graduate students.")
Refreshments will be served in the Common Room at 3:15 p.m.
