Abstract
In this paper, an explicit construction of compactly supported prewavelets on linear finite element spaces is introduced on non-uniform meshes on polyhedron domains and on boundaries of such domains. The obtained basas are stable in the Sobolev spaces Hr for |r| < 3/2. The only condition we need is that of uniform refinements. Compared to existing prewavelets bases on uniform meshes, with our construction the basis transformation from wavelet- to nodal basis (the wavelet transform) can be implemented more efficiently.
