Trial function method is applied to solve generalized mKdV (GmKdV for short) equations. It is shownthat GmKdV equations with a real number parameter can be solv
Hamiltonian of a one-dimensional Bose Hubbard model is re-formulated by using differential realization of the boson algebra.Energy matrices can then be generate
