This result generalizes a results of F. Pacard and the second author where the existence of a nondegenerate critical point of the scalar curvature of the Riemannian manifold was required. %G English %2 https://hal.science/hal-01266512/document %2 https://hal.science/hal-01266512/file/delay_sicbaldi1.pdf %L hal-01266512 %U https://hal.science/hal-01266512 %~ UNIV-AVIGNON %~ CNRS %~ UNIV-AMU %~ EC-MARSEILLE %~ INSMI %~ I2M %~ I2M-2014- %~ TDS-MACS %~ LMA-UAPV
