- From his numerous contributions through research articles, books, and conference volumes we just mention his[Vlastimil Dlab's] work on the representation theory of hereditary algebras in the mid-seventies of the last century, joint with C.M. Ringel, laying the foundations of, in particular, tame hereditary representation theory over arbitrary fields, a theory still at the centre of interest.
Usage notes
Almost always used in the singular, but often qualified by the category of structure represented.
