%0 Book %T Orthogonality on cosets %A Knörr, Reinhard %S Preprints aus dem Institut für Mathematik %D 2005 %C Germany; Rostock %G English %F 1987059913 %O Reinhard Knörr %X We present a version of the orthogonality relations for group characters which appears to be new - at least in this generality. The proof given uses only Maschke's theorem and Schur's lemma. Among other consequences, Burnside's result on the existence of zeros for non-linear irreducible characters is generalized. %L 510 %9 Text %R 10.18453/rosdok_id00005890 %U https://purl.uni-rostock.de/rosdok/id00005890 %U https://doi.org/10.18453/rosdok_id00005890
