Vb. Derjagin et al., N=2 superintegrable f-Toda mapping and super-NLS hierarchy in (1 vertical bar 2) superspace, PHYS ATOM N, 61(11), 1998, pp. 1990-1996
A new integrable N = 2 supersymmetric f-Toda mapping in (1 \ 2) superspace,
acting like the symmetry transformation of N = 2 supersymmetric NLS hierar
chy, is proposed. The first two Hamiltonian structures and the recursion op
erator connecting all evolution systems and Hamiltonian structures of the N
= 2 super-NLS hierarchy are constructed explicitly by using only the condi
tions of invariance with respect to the f-Toda mapping. A new representatio
n for its Hamiltonians is observed.
