Haar Wavelets on Spherical Triangulations

  • Daniela Roşca
Part of the Mathematics and Visualization book series (MATHVISUAL)

Summary

We construct piecewise constant wavelets on spherical triangulations, which are orthogonal with respect to a scalar product on L2(\(\mathbb{S}\)2). Our classes of wavelets include certain wavelets obtained by Bonneau and by Nielson et al. We also prove the Riesz stability and show some numerical experiments.
