Clifford theory and endoisomorphisms.
This paper extends some of the author's earlier results [J. Algebra 321, No. 12, 3620-3642 (2009; Zbl 1186.20011); ibid. 3643-3658 (2009; Zbl 1186.20012)] that assign to each Clifford theory an element of the Brauer-Clifford group, from the case of characteristic 0 to the case of arbitrary characteristic. To do this, the concept of an \textit{endoisomorphism} is introduced and related to some classical concepts used in Clifford theory of finite groups. Due to the technical nature of the subject, we refer to the original paper for the precise statement of the results.
