@Book{1987059913, author="Kn{\"o}rr, Reinhard", title="Orthogonality on cosets", series="Preprints aus dem Institut f{\"u}r Mathematik", year="2005", address="Germany; Rostock", abstract="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.", note="Reinhard Kn{\"o}rr", doi="10.18453/rosdok_id00005890", url="https://purl.uni-rostock.de/rosdok/id00005890", url="https://doi.org/10.18453/rosdok_id00005890", language="English" }
