A Weight Theory for Unitary Representations
Canadian Journal of Mathematics, 1966Over a field of characteristic 0 certain of the simple Lie algebras have a root theory, namely those called “split” in Jacobson's book (3). We shall assume some familiarity with the subject matter of this book. Then the finite-dimensional representations of these Lie algebras have a weight theory.

On Unitary Representations of the Inhomogeneous Lorentz Group
Nuclear Physics B - Proceedings Supplements, 1939It is perhaps the most fundamental principle of Quantum Mechanics that the system of states forms a linear manifold,1 in which a unitary scalar product is defined.2 The states are generally represented by wave functions3 in such a way that φ and constant multiples of φ represent the same physical state.

On pseudo-unitary representations
Czechoslovak Journal of Physics, 1987The structure of representations of a group on a finite dimensional complex vector space with a non-degenerate invariant (indefinite) inner product is analysed in terms of layers of Gupta-Bleuler triplets.

Unitary Representations of Supergroups
1986To find the obstructions to integrability of representations of superalgebras, we have studied the problem of deciding on a fruitful definition of supergroup. The most natural definition turns out to be a semidirect product, G = X·Go, where Go is a Lie group and the invariant subsupergroup is in a certain sense nilpotent.
