Polynomial realization of the Uq(sl(3)) Gel'fand–(Weyl)–Zetlin basis
An explicit realization of the Uq(sl(3)) Gel'fand–(Weyl)–Zetlin (GWZ) basis as polynomial functions in three variables (real or complex) is given. This realization is obtained in two complem...

The perturbed Korteweg–de Vries equation considered anew
The perturbed Korteweg–de Vries equation is studied in a new way by a Green's function formalism without use of inverse scattering methods. The Green's function is determined by employing the B&a...

It is shown that the construction carried out by Cariñena and Ibort [J. Math. Phys. 29, 541–545 (1988)] involving nonsymplectic actions of Lie groups gives rise to "true" noncentral extensions of the corresponding Lie algebras. ©1997 American Institute of Physics.
