FROM CLASS FIELD THEORY TO ZETA SPECTRAL TRIPLES (FROM CLASS FIELD THEORY TO ZETA SPECTRAL TRIPLES)
I will cover recent joint work with C. Consani and H. Moscovici on the long search for spectral triples associated to the low lying zeros of zeta (infrared) as well as to ultraviolet zeros and …

CORRESPONDENCES BETWEEN GRAPH C*-ALGEBRAS (CORRESPONDENCES BETWEEN GRAPH C*-ALGEBRAS)
We describe proper correspondences from graph C*-algebras to arbitrary C*-algebras by K-theoretic data. If the target C*-algebra is a graph C*-algebra as well, we may lift an isomorphism and its inverse on a certain invariant …

THE LADDER (THE LADDER)
We present a new method of establishing a bijective correspondence - in fact, a lattice isomorphism - between invariant ideals of C*-algebras and their crossed products by a fixed locally compact group. It was already …

SUGATO MUKHOPADHYAY (SISSA, Trieste, Italy)
ALGEBRAIC AND SPECTRAL TORSIONS ON THE ALMOST COMMUTATIVE GEOMETRY OF DOUBLED MANIFOLDS
I will present a construction of a noncommutative second order differential calculus on the algebra of smooth functions on the product of a manifold with the two-point space. This involves a modification of the standard …

VAKSMAN-SOIBELMAN ODD QUANTUM SPHERES AND COMPLEX QUANTUM PROJECTIVE SPACES REVISITED
Odd-dimensional quantum spheres were introduced in 1990 by Vaksman and Soibelman as quantum homogeneous spaces of Woronowicz's quantum unitary groups. Since then, they have served as major examples for testing ideas about non-commutative spaces. In …

REDUCTIONS OF QUANTUM PRINCIPAL BUNDLES
We develop the theory of reductions of quantum principal bundles over projective bases. We show how the sheaf-theoretic approach can be effectively applied to certain relevant examples such as the Klein model for the projective …

THE CUNTZ SEMIGROUP AND THE STRUCTURE OF C*-ALGEBRAS
The Cuntz semigroup, introduced over 40 years ago by J. Cuntz, has become a valuable tool for understanding the structure of C*-algebras. Building on A. Toms’ pioneering work in the early 2000s, which produced the …
