Automorphisms and ultraspecial groups

open access: yesJournal of Algebra, 1979
In [l], we have introduced the classes GCZ( p) and U(p) of semi-extraspecial and ultraspecial p-groups, namely @Z(p) = {X 1 X is a finite p-group, X’ # 1, Nmax Z(X) * X/N is extraspecial} and U(p) = {X j XE EK!!( p), r(X) = *r(X)}. If X is a semi-extraspecial p-group, then X is a special group of even rank with r(X’) C GF(p”)}, (a, b, ~)(a’, b’, c’) =

The Virasoro Algebra and Some Exceptional Lie and Finite Groups

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We describe a number of relationships between properties of the vacuum Verma module of a Virasoro algebra and the automorphism group of certain vertex operator algebras.
