gmathimatikos is on a distinguished road
Hi
Does anyone knows if it is possible to construct a modal orthogonal basis on polygons? Something like the Legendre polynomial basis on quadrilaterals or triangles? The problem with triangles or quadrilaterals is that i find it very hard to implement specially on triangles the collapsed coordinate transformation and the tensor product. It would be very convenient for me if I could directly construct a modal base on polygons
