Invariant meshless discretization schemes [PDF]

Journal of Physics A: Mathematical and Theoretical, 2013
A method is introduced for the construction of meshless discretization schemes which preserve Lie symmetries of the differential equations that these schemes approximate. The method exploits the fact that equivariant moving frames provide a way of associating invariant functions to non-invariant functions.
