I. Mukhopadhyay et A. Roychowdhury, ON INTEGRABLE AND SUPER-INTEGRABLE SYSTEMS WITH EXPLICIT X-DEPENDENCE- AN ADLER-KOSTANT-SYMES APPROACH, Physics letters. A, 241(4-5), 1998, pp. 262-268
Explicitly X-dependent integrable equations are obtained by using the
AKS theorem in the loop algebraic setting of the SL(2,C) algebra and i
ts super-extension. The Hamiltonian structures of these equations are
also deduced and discussed, by using Dirac reduction. The supersymmetr
ic KdV equation with explicit X-dependence is deduced and shown to be
completely integrable. In the whole analysis we have not assumed any n
ontrivial variation of the spectral parameter with respect to space or
time. (C) 1998 Elsevier Science B.V.
