The algebraic properties of the space- and time-dependent one-factor model of commodities
A. Paliathanasis, R. M. Morris, P. G. L. Leach
We consider the one-factor model of commodities for which the parameters of the model depend upon the stock price or on the time. For that model we study the existence of group-inv…

Symmetry analysis and algebraic structures of the Hu-Paz-Zhang Master Equation
Richard M. Morris, Peter G. L. Leach
We apply the Lie Theory of continuous groups to investigate the symmetries of the Hu-Paz-Zhang Master Equation which arises in the modelling of the interaction of a harmonic oscill…
