A personal encyclopedia for mathematics and physics, mainly about
- Geometric representation theory: Quantization, the orbit method, abstract harmonic analysis, automorphic forms.
- Noncommutative geometry: Poisson geometry, Baum-Connes assembly, Kasparov’s KK-theory, index theory.
- Higher categorical geometry: Stacks and gerbes, topos theory, generalized spaces.
