We investigate the properties of univariate MRA Riesz wavelets. In particular we obtain a generalization to semiorthogonal MRA wavelets of a well-known representation theorem for orthonormal MRA ...

We construct wavelet Riesz bases for the usual Sobolev spaces of divergence free functions on (0, 1) n that have vanishing normals at the boundary. We give a simultaneous space-time variational ...
