Cartan connections and integrable vortex equations
نویسندگان
چکیده
We demonstrate that integrable abelian vortex equations on constant curvature Riemann surfaces can be reinterpreted as flat non-abelian Cartan connections. By lifting to three dimensional group manifolds we find higher analogues of vortices. These configurations are also encoded in a connection. give examples different types interpreted this way, and compare contrast representation with the symmetric instanton representation.

متن کاملIntegrable and non-integrable equations with peakons
We consider a one-parameter family of non-evolutionary partial differential equations which includes the integrable Camassa-Holm equation and a new integrable equation first isolated by Degasperis and Procesi. A Lagrangian and Hamiltonian formulation is presented for the whole family of equations, and we discuss how this fits into a bi-Hamiltonian framework in the integrable cases. The Hamilton...
متن کاملCartan Connections and Natural and Projectively Equivariant Quantizations
In this paper, we analyse the question of existence of a natural and projectively equivariant symbol calculus, using the theory of projective Cartan connections. We establish a close relationship between the existence of such a natural symbol calculus and the existence of an sl(m+1,R)equivariant calculus over R in the sense of [15, 1]. Moreover we show that the formulae that hold in the non-cri...
