  1. Characteristic cone given by equation ideal

    2. This program takes the generators of the cone and the partial difference equations of discrete autonomous nD system as inputs and gives a 'yes/no' certificate according to whether the given cone is a characteristic cone for the given system or not.

  2. Characteristic cone given by equation module

    3. This program takes the generators of the cone and the kernel representation matrix of discrete autonomous nD system as inputs and gives a 'yes/no' certificate according to whether the given cone is a characteristic cone for the given system or not.

  3. Solution of partial differenrial equations

    4. Here Oberst-Riquier algorithm is used for solving the given set of partial differenrial equation(s). The output of this algorithm is in a power series form.
