Virasoro 3-algebra from scalar densities
T a Larsson
It is shown that the ternary Virasoro-Witt algebra of Curtright, Fairlie and Zachos can be constructed by applying the Nambu commutator to the vect(1) realization on scalar densiti…
Constrained Fock spaces as Virasoro modules
T. A. Larsson
The method of constrained Hamiltonian systems can be used to reduce Fock modules. It is applied to the Virasoro algebra, where a possibly new realization is found.
Diffeomorphism group and conformal fields
T. A. Larsson
Conformal fields are a new class of modules which are more general than tensor fields. The corresponding diffeomorphism group action is constructed. Conformal fields are…
Vect(N) conformal fields and their exterior derivatives
T. A. Larsson
Conformal fields are a recently discovered class of representations of the algebra of vector fields in dimensions. Invariant first-order differential operators (exterior deriva…
