On equivariant harmonic maps defined on a Lorentz manifold
Annales de l'Institut Fourier, Tome 41 (1991) no. 2, pp. 511-518.

Nous démontrons à l’aide du principe du minimax qu’il existe une infinité d’applications harmoniques, G-équivariantes, définies sur une variété lorentzienne donnée et à valeurs dans une riemannienne compacte.

In this paper, we prove by using the minimax principle that there exist infinitely many G-equivariant harmonic maps from a specific Lorentz manifold to a compact Riemannian manifold.
