   abstract = {We report the existence, and study mobility and interactions of gap
polariton solitons in a microcavity with a periodic potential, where
the light field is strongly coupled to excitons. Gap solitons are
formed due to the interplay between the repulsive exciton-exciton
interaction and cavity dispersion. The analysis is carried out in
an analytical form, using the coupled-mode (CM) approximation, and
also by means of numerical methods.},
