Nature of problem:The construction of the Lie symmetry superalgebra of a system of Grassmann-valued differential equations (SGVDE) is a first step in the resolution of such a system. The next step would be the use of symmetry reduction method to get a simpler system which could be solved easily. | ||

Solution method:The algorithm to calculate the Lie supersymmetries for Grassmann-valued differential equations is a direct extension of the one described in [1]. All the steps of these calculation techniques are now modelled into a MAPLE program. | ||

Restrictions:The time consuming becomes higher when the order, as well as the number of odd dependent and independent variables of the SGVDE is increasing. | ||

Unusual features:GLie is the first MAPLE program that calculates the determining equations for both usual and Grassmann-valued systems of partial differential equations. The resolution of such equations leads to the construction of Lie superalgebras of symmetries. | ||

Running time:It depends strongly on the SGVDE to be solved. Typical running time is given in section 5. | ||
