Jacquet functors and unrefined minimal \(K\)-types. (English) Zbl 0860.22006
The authors define the notion of unrefined minimal \(K\)-type for a reductive group defined over a non-archimedean local field. They further define the depth of a representation. The authors determine the relationship between unrefined minimal \(K\)-types and the Jacquet functors. Analogues of fundamental results of Borel are proved for representations of depth zero.
