In this paper, we prove by using the minimax principle that there exist infinitely many -equivariant harmonic maps from a specific Lorentz manifold to a compact Riemannian manifold.
Nous démontrons à l’aide du principe du minimax qu’il existe une infinité d’applications harmoniques, -équivariantes, définies sur une variété lorentzienne donnée et à valeurs dans une riemannienne compacte.
