SUMMARY:Analysis Seminar: Realization of von Neumann regular rings - Joan Bosa (Barcelona)
DESCRIPTION:Abstract: The realization problem for von Neumann (vN) regular rings asks whether all conical refinement monoids arise from monoids induced by the projective modules over a vN regular ring. In this talk we will sketch the proof of the last developments done in this direction. Joint work with P.

SUMMARY:Analysis Seminar: Structure preserving *-isomorphisms of (groupoid) C*-algebras - Kevin Aguyar Brix (University of Copenhagen)
DESCRIPTION:Abstract: Groupoids have proven very useful in understanding and encoding topological dynamics into C*-algebras. This point of view emphasizes the importance of *-isomorphisms which preserve diagonals or intertwine specified actions. I will emphasize how these structure preserving maps arise naturally in the study of topological dynamics (in particular\, orbit equivalences) but...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10263

SUMMARY:Analysis Seminar: Lower bounds on the Hausdorff dimension of the Rauzy gasket - Carlos Matheus Silva Santos (Ecole Polytechnic/CNRS)
DESCRIPTION:Abstract: The classical thermodynamical formalism of Ruelle\, Bowen\, ... is a beautiful theory allowing to treat several natural questions including the computation of the Hausdorff dimension of conformal repellers in terms of the spectral features of certain transfer operators. Nevertheless\, the problem of giving bounds for the Hausdorff dimension of...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10447

SUMMARY:Analysis Seminar: Non-commutative Poincaré Duality of the irrational rotation algebra - Anna Duwenig (University of Victoria)
DESCRIPTION:Abstract: The irrational rotation algebra is known to be self-dual in a KK-theoretic sense. The required K-homology fundamental class was constructed by Connes out of the Dolbeault operator on the 2-torus\, but so far\, there has not been an explicit description of the dual element. In this talk\, I will geometrically...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10446

SUMMARY:Analysis Seminar: C*-algebras from actions of congruence monoids - Chris Bruce (University of Victoria)
DESCRIPTION:Abstract: Congruence monoids in the ring of integers are given by certain unions of arithmetic progressions. To each congruence monoid\, there is a canonical way to associate a semigroup C*-algebra. I will explain this construction and then discuss joint work with Xin Li on K-theoretic invariants. I will also indicate how...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10445

SUMMARY:Analysis Seminar: KMS states on the crossed product C*-algebra of a homeomorphism - Johannes Christensen (Aarhus University)
DESCRIPTION:Abstract: Since its introduction\, the theory of operator algebras has been interacting closely with the theory of dynamical systems. A classical way to associate a C*-algebra to a dynamical system is via the crossed product C*-algebra of a homeomorphism. If a homeomorphism acts on a compact metric space X\, one can...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10407

SUMMARY:Analysis Seminar: Amenability and approximation properties of C*-dynamical systems - Alcides Buss (Federal University of Santa Catarina)
DESCRIPTION:Abstract: In this talk I will discuss some basic notions of amenable actions of groups on C*-algebras and present some new developments into this direction. These are certain approximation properties that are closely related to (relative) nuclearity of the corresponding crossed products. The actions involved here could be partial (i.e. by...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10413

SUMMARY:Analysis Seminar: Approximation on the Cantor set and other related fractals - Demi Allen (University of Bristol)
DESCRIPTION:Abstract: The aim of this talk will be to consider (Diophantine) approximation on general "Cantor-like" fractals. In 2007\, Levesley\, Salp\, and Velani considered the problem of approximating points in the middle-third Cantor set at a given rate of approximation by rational numbers which have denominators which are powers of 3. They...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10418

DESCRIPTION:Abstract: We will introduce the notion of "asymptotic expansion" recently definedby Li\, Nowak\, Spakula and Zhang and give operator algebraic motivationfor their study. We will explore this definition in the familiar settingof Cayley graphs\, and show that this leads to a C*-algebraiccharacterisation of usual expanders for graphs...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10461

Most of these can be studied conveniently in the framework of topological groupoids. In...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10480

DESCRIPTION:Abstract: Derivations are an important class of linear maps in Banach algebra theory. It would be convenient if we could extend a derivation defined on a closed subalgebra to a derivation defined on the whole Banach algebra. This is certainly not the case. However\, under some fairly...\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10481

SUMMARY:Analysis Seminar: Gabor Analysis over Quasicrystals meets Operator Algebras - Petter Nyland (NTNU Trondheim)
DESCRIPTION:Abstract: Two fundamental families of operators on the Hilbert space of square-integrable functions are time shifts and frequency shifts. These are the central players in time-frequency analysis. The subfield of Gabor analysis is concerned with frames that arise from time-frequency shifts of a fixed window function\, so-called Gabor frames....\N\NMore information: http://www.gla.ac.uk/schools/mathematicsstatistics/events/details/?id=10462
