Abstract. We first formulate quasi-intersection problems concerning multivalued mappings and give some sufficient conditions to the existence of their solutions. In particular, we establish several results on the existence of solutions for quasi-equilibrium problems and of fixed points of l.s.c and u.s.c mappings.
