recommendations! Published in 2024 at "Acta Mathematica Hungarica"

DOI: 10.1007/s10474-024-01408-z

Abstract: We study some families of finite groups having inner class-preserving automorphisms. In particular, let G be a finite group and S be a semidihedral Sylow 2-subgroup. Then, in both cases when either Sym(4) is not… read more here.

DOI: 10.1007/s13370-017-0540-6

Abstract: In this paper, we introduce the notion of a central B-automorphism of a finite B-algebra. Also some properties of a finite B-algebra and B-automorphism algebra are investigated. read more here.

DOI: 10.1142/s0219498826502282

Abstract: In this paper, we mainly investigate the class-preserving automorphisms of finite groups whose Sylow subgroups of odd order are all cyclic, with a semi-dihedral Sylow [Formula: see text]-subgroup. We show that finite groups with this… read more here.

DOI: 10.1556/012.2021.58.1.1486

Abstract: We study the effect on sections of a soluble-by-finite group G of finite rank of an almost fixed-point-free automorphism φ of G of finite order. We also elucidate the structure of G if φ has… read more here.
