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…
