Abstract
The Cosmic Microwave Background (CMB) constitutes a "photography" of the early universe. A directional wavelet analysis of the spherical maps of the CMB anisotropies could bring fundamental elements to the comprehension of the evolution and the structure of our universe. To carry out this wavelet analysis, we need efficient algorithms on the sphere.
