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.
