Title |
Support theories and tensor triangular geometry in pictures |
Abstract |
Tensor triangular geometry associates a rich geometric structure, the spectrum, to a “nice” category
where one can add, subtract and multiply objects. Examples include modules over a commutative ring and representations of a finite group. I’ll give an introduction to tensor triangular geometry via the classical notion of support and present some examples of calculations of spectra where pictures of different degrees of beauty will appear. The examples will fall into two families: when the multiplicative unit has a lot of symmetries – going back to the work of D. Quillen in the 70s - and when it does not. Based on joint work with T. Barthel, D. Benson., S. Iyengar, H. Krause and V. Serganova, A. Sherman. |
