Noncommutative instantons and twisted conformal symmetries
I report on recent work on deformation of spaces, in particular spheres, and deformation of vector bundles which are relevant in physics, notably monopole and instanton bundles.A first class of examples consists of toric noncommutative manifolds which were introduced out of cycles in homology. These examples have non-trivial global features and can be endowed with the srtucture of noncommutative manifold, defined in terms of Connes spectral triple. In particular,
noncommutative spheres are isospectral deformations of usual spherical geometries. Instanton bundles and Yang-Mills duality equations can be introduced and a geometric analysis paralleling the one on commutative spaces can be performed. Twisted conformal symmetries are used to generate instanton solutions (i.e. solutions of the duality equations); these are absolute minima of the Yang-Mills functionals.A second class of examples is made of spaces coming from quantum groups, some of which can again be endowed with a spectral triple. Also one can construct generalizations of instanton bundles.

Abstract:
The interesting actions of the finite groups on the rotation algebra are those of Z mod2, Z mod 3, Z mod 4, and Z mod 6. For example the action of Z mod 4 is generated by the "noncommutative Fourier transform", the automorphism determined by the assignments of U to V and of V to U*. We prove that for the irrational rotation algebra, the cross product by any of these four actions is an AF-algebra. This has been known for some time for the action of Z mod 2, and Z mod 4, but the other cases are new. The proofs combine a variety of methods. In particular, they use the fact that the actions in question have the tracial Rokhlin property, Lin's classification result for simple separable C*-algebras with tracial rank zero and satisfying the Universal Coefficient Theorem and the Baum-Connes conjecture for countable amenable groups.

Spectra of Algebras of Entire Functions on Banach spaces
An entire function on a Banach space is said to be a function of bounded type if it is bounded on bounded subsets. We will consider the spectrum (set of maximal ideals) of the algebra of bounded analytic functions on a Banach space and describe a natural linear structure of the spectrum.

Amenability and topology.
In attempting to generalize the analysis of yesterday talk from Z to other groups, one encounters the amenability property that G. Yu calls "property A". This property has significant topological implications. We shall explain how one passes from a representation theoretic property such as property A to results about the homotopy invariance of various characteristic numbers and their "secondary" generalizations.
