Computational Algorithms for Invariant Reduction of Variational Forms

Kostya Druzhkov, Alexey Shevyakov

Symmetry reductions of partial differential equations (PDEs) inherit more geometric structures than other types of reductions: invariant conservation laws, variational structures,…

Invariant Reduction for Partial Differential Equations. IV: Symmetries that Rescale Geometric Structures

Kostya Druzhkov, Alexei Cheviakov

For a system of partial differential equations admitting point, contact, or higher symmetries, the framework of invariant reduction systematically computes how invariant geometric…
