Dr. Robert-Jan Slager covered a selection of our recent work on topological characterizations in a rather colloquial style. In particular, he reviewed how constraints on symmetry eigenvalues can directly be linked to topological invariants, reproducing involved K-theory evaluations from a simple algorithmic point of view. The resulting conditions can then be extended to contemporary classification schemes by comparing to real space configurations, going by the name topological quantum chemistry or symmetry indicators.
