Conjugacy classes in linear groups
Abstract Let G belong to one of the three families of complex classical linear groups or to one of the seven families of corresponding real forms. Let L denote its Lie algebra. We give a simple andExpand

Normal forms for real linear Hamiltonian systems with purely imaginary eigenvalues
This note gives a concise algorithm for computing a normal form for a real linear Hamiltonian differential equatin which has purely imaginary eigenvalues. This algorithm is then applied to theExpand

Some computations involving simple Lie algebras
TLDR
This article is a report of some computations that were done recently with the hope of understanding an apparently simple, though as yet unanswered, question in linear algebra. Expand

The Schur multipliers of the Mathieu groups
The Mathieu groups are the finite simple groups M 11 , M 12 , M 22 , M 23 , M 24 given originally as permutation groups on respectively 11, 12, 22, 23, 24 symbols. Their definition can best be foundExpand
