Research topics

Which keywords describe Bernhard Keller's research?

The keywords of their largest research topics: Cohomology, Cluster Algebras, Triangulated Categories, Deformations, Hom-Lie Algebras, Symplectic Geometry, Deformation Quantization and Poisson Manifolds.

Size is their works in the topics tagged with each word, from their 8 largest topics. Each links to the topic it comes from most. The words come from the keyword list OpenAlex gives each topic, not from the text of the papers, so a word can appear that none of the papers uses.
