2106a - Mini-Workshop: Non-semisimple Tensor Categories and Their Semisimplification (online meeting)

[OWR-2021-7] Workshop Report 2021,7 (2021) - (07 Feb - 13 Feb 2021)

Finite tensor categories are, despite their many applications and great interest, notoriously hard to classify. Among them, the semisimple ones (called fusion categories) have been intensively studied. Those with ...
2142a - Mini-Workshop: Three Facets of R-Matrices (hybrid meeting)

[OWR-2021-51] Workshop Report 2021,51 (2021) - (17 Oct - 23 Oct 2021)

By definition, an $R$-matrix with spectral parameter is a solution to the Yang-Baxter equation, introduced in the 1970's by C.N. Yang and R.J. Baxter. Such a matrix encodes the Boltzmann weights of a lattice model of ...
