BPST instanton and Spin from inequivalent quantizations
David McMullan, Izumi Tsutsui
We present a simple alternative to Mackey's account of the (infinite) inequivalent quantizations possible on a coset space G/H. Our reformulation is based on the reduction ${\rm G…
On the emergence of gauge structures and generalized spin when quantizing on a coset space
David McMullan, Izumi Tsutsui
It has been known for some time that there are many inequivalent quantizations possible when the configuration space of a system is a coset space G/H. Viewing this classical system…
The vacuum preserving Lie algebra of a classical W-algebra
L. Feher, L. O'Raifeartaigh, I. Tsutsui
We simplify and generalize an argument due to Bowcock and Watts showing that one can associate a finite Lie algebra (the `classical vacuum preserving algebra') containing the Möbiu…
On the Completeness of the Set of Classical W-Algebras Obtained from DS Reductions
L. Feher, L. O'Raifeartaigh, P. Ruelle +1
We clarify the notion of the DS --- generalized Drinfeld-Sokolov --- reduction approach to classical -algebras. We first strengthen an earlier theorem which showed that a…
