Abstract
Time-dependent quadratic Hamiltonians have diverse applications. We construct such a Hamiltonian from a representation of the elements of the algebra sl(2, R)circle plus(s) W with each element having an independent, time-dependent coefficient. We demonstrate that the corresponding Schrodinger equation possesses the Lie algebra. {sl(2, R) circle plus(s) W} circle plus(s) infinity A(1) and show how to construct the wave functions using this representation.
