Underdetermined Systems of Partial Differential Equations
Physics and Astronomy
Mathematics and Natural Sciences
This paper examines underdetermined systems of partial differential equations in which the independent variables may be classical c-numbers or even quantum operators. One can view an underdetermined system as expressing the kinematic constraints on a set of dynamical variables that generate a Lie algebra. The arbitrariness in the general solution reflects the freedom to specify the dynamics of such a system. (C) 2000 American Institute of Physics. [S0022-2488(00)02009-0].
