Cohomology and Decomposition of Tensor Product Representations of SL(2,R)
Andre van Tonder
We analyze the decomposition of tensor products between infinite dimensional (unitary) and finite-dimensional (non-unitary) representations of SL(2,R). Using classical results on i…

On the Representation Theory of Negative Spin
Andre van Tonder
We construct a class of negative spin irreducible representations of the su(2) Lie algebra. These representations are infinite-dimensional and have an indefinite inner product. We…

Ghosts as Negative Spinors
Andre van Tonder
We study the the properties of a BRST ghost degree of freedom complementary to a two-state spinor. We show that the ghost may be regarded as a unit carrier of negative entropy. We…
