The integrable, (1+1) Gross-Pitaevskii (GP-) equation with hermitian property is extended to chaotic behaviour as part of general complex fields within the sl(2,C) algebra for Lax pairs. Furthermore, we prove the involution property of conserved quantities in the case of GP-type equations with an arbitrary external potential. We generalize the approach of Lax pair matrices to arbitrary spacetime dimensions and conclude for the type of nonlinear equations from the structure constants of the underlying algebra. One can also calculate conserved quantities from loops within the (N-1) dimensional base space and the mapping to the manifold of the general SL(n,C) group or a sub-group, provided that the resulting fibre space is of nontrivial homotopic kind.
