Abstract
A variational wave function to describe the ground-state properties of the attractive Hubbard model is presented. The function is complementary to the Gutzwiller wave function for positive U. The results are in agreement with the canonical transformation which is known to relate the attractive and repulsive Hubbard models for all electronic densities.
