This seminar will focus on various aspects of Functional Analysis. It usually meets on Thursdays at 2:30pm in MATH 350. If you have questions regarding this seminar, please contact Robin Deeley, Carla Farsi, Judith Packer or Alonso Delfin.

Thu, Jan. 22 2:30pm (MATH 3…	Dorin Dumitrascu (Adrian College) X I will discuss some aspects of the bivariant K-theory developed by Le Gall. (P. Y. LeGall, Th\'eorie de Kasparov \'equivariante et groupo\"{\i}des. I, K-Theory 16 (1999), 361--390.) Equivariant KK-theory for groupoids acting on C*-algebras (after Le Gall)
Thu, Jan. 29 2:30pm (MATH 3…	Dorin Dumitrascu (Adrian College) X I will give the definition of Le Gall for the equivariant KK-theory under the action of a Hausdorff groupoid, propose a construction for locally compact locally Hausdorff groupoids, and work out an example coming from foliations. Equivariant KK-theory for groupoids acting on C*-algebras (part 2)
Thu, Feb. 12 2:30pm (MATH 3…	Robin Deeley (CU Boulder) X I will introduce a class of dynamical systems called shifts of finite type. There are a number of C-algebras one can construct from a shift of finite type. I will discuss properties of these C-algebras such as rational Poincare duality and rational isomorphism. Rationalizing shifts of finite type - Part I

Thu, Mar. 26 2:30pm (MATH 3…	Karen Strung (Institute of Mathematics of the Czech Academy of Sciences) X A common strategy for understanding the structure of a C-algebra is to decompose it into more manageable subcomponents—such as its lattice of ideals or subspaces arising from a grading—with the aim of reconstructing global information from local data and the way these pieces interact. Conversely, one can begin with structured pieces and ask how to assemble them into a C-algebra. A well-studied example of this approach is the theory of Fell bundles over discrete groups. In this talk, we present a generalization of Fell bundles from discrete groups to unital based rings, a broader algebraic framework that accommodates richer types of gradings. We describe how to construct a reduced C*-algebra of sections associated to such a bundle and discuss examples arising from group gradings and coactions of compact quantum groups. This is joint work in progress with Suvrajit Bhattacharjee, Bhishan Jacelon, and Réamonn Ó Buachalla. Fell bundles over unital based rings Sponsored by the National Science Foundation

Thu, Apr. 23 11am (MATH 220)	Roberto Hernandez Palomares (University of Waterloo) X Spin models for singly-generated Yang-Baxter planar algebras are known to be determined by certain highly-regular classical graphs such as the pentagon or the Higman-Sims graph, which are extremely rare. Examples of spin models include the Jones and Kauffman polynomials. We will discuss the notion of higher-regularity for quantum graphs and give new examples of non-classical graphs yielding spin models. Time allowing, we will discuss some applications to quantum groups, topology and quantum information. Quantum graphs and spin models Sponsored by the Meyer Fund
Thu, Apr. 23 2:30pm (MATH 3…	J. Quigg (Arizona State University) X One approach to identifying the C*-algebra of a product system over N^k is to build a representation of it with the aim of applying the Gauge-Invariant Uniqueness theorem. The main problem is how to build the representation. This is complicated by the commutativity of N^k - so many balanced tensor-product correspondences are isomorphic. I'll show how an abstract categorical result of Fowler-Sims can be used to surmount this obstacle. Joint work with Valentin Deaconu, Menevse Eryuzlu Paulovicks, and S. Kaliszewski.
