Algebra/Topology Seminar, Bulent Tosun, University of Alabama
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle : Contact geometry in low dimensions Abstract: This series of talks will be about explaining some fundamental open problems in three-dimensional contact geometry. This third talk will be on overtwisted vs. tight dichotomy (or flexible vs. rigid), and existence problem of tight contact structures.
Analysis Seminar – Edward Timko, Indiana University
227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle : On polynomial n-tuples of commuting isometries Abstract : We extend some of the results of Agler, Knese, and McCarthy to n-tuples of commuting isometries for n>2. Let V=(V_1,...,V_n) be an n-tuple of a commuting isometries on a Hilbert space and let Ann(V) denote the set of all n-variable polynomials p such that p(V)=0.

227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesAbstract: A classification of partial isometries defined on a Hilbert space can be made in terms of positions that two subspaces, the initial space and the final space, form. When the orthogonal projections onto two subspaces commute, any power of the partial isometry remains also a partial isometry. This type of partial isometry is called
Algebra/Topology Seminar – Sergio Fabi, UA Department of Physics
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Lie Groupoid Abstract: Motivation and introduction to the general theory of groupoid, Lie groupoid and Lie algebroid. Few examples are given, in particular the gauge groupoid.
Analysis Seminar – Carlos Pérez (University of the Basque Country and Ikerbasque, Spain)
302 Gordon Palmer HallTitle: Rough Singular Integrals: A1 theory Abstract: In this mostly expository talk we will discuss new results for rough Singular Integral Operators involving A1 weights. These are convolution operators whose kernels do not satisfy the standard regularity conditions (Lipschitz or Dini). Being more precise we will discuss estimates for these operators in the context of

228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Atiyah sequence Abstract: Review of the theory of exact sequences to define a connection on a principal bundle. The construction of a gauge theory of gravity on a Lie algebroid is considered.
Last Math Undergrad Tea of the Semester and Putnam Exam Pep Rally
302 Gordon Palmer HallOn Saturday, December 3, the UA Putnam team will compete in the 77th annual Putnam Exam. Come to tea, cheer on the team and celebrate the end of the semester. There will be special refreshments and a visit by Big Al!
Analysis Seminar – Geoff Diestel, Texas A&M of Central Texas
227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Determining Convex Bodies from Central Sections Abstract: Barker and Larman posed a problem which asks if a convex body in real n-space is uniquely determined by the volumes of its hyperplane sections supported by an internal compact convex set. A survey of some partial results along with the Minkowski uniqueness theorem are presented along
