The work of Alain Connes has cut a wide swath across several areas of math- ematics and physics. Reflecting its broad spectrum and profound impact on the contemporary mathematical landscape, this collection of articles covers a wealth of topics at the forefront of research in operator algebras, analysis, noncommutative geometry, topology, number theory and physics.







Specific themes covered by the articles are as follows:

  • entropy in operator algebras, regular C*-algebras of integral domains, properly infinite C*-algebras, representations of free groups and 1-cohomology, Leibniz seminorms and quantum metric spaces;
  • von Neumann algebras, fundamental Group of II1 factors, subfactors and planar algebras;
  • Baum-Connes conjecture and property T, equivariant K-homology, Hermitian K-theory;
  • cyclic cohomology, local index formula and twisted spectral triples, tangent groupoid and teh index theorem;
  • noncommutative geometry and space-time, spectral action principle, quantum gravity, noncommutative ADHM and instantons, non-compact spectral triples of finite volume, noncommutative coordinate algebras;
  • Hopf algebras, Vinberg algebras, renormalization and combinatorics, motivic renormalization and singularities;
  • cyclotomy and analytic geometry over F1, quantum modular forms;
  • differential K-theory, cyclic theory and S-cohomology.
