Sažetak

The existence of common fixed points is established for three
mappings where T is either generalized (f,g)-nonexpansive or
asymptotically (f,g)-nonexpansive on a set of fixed points
which is not necessarily starshaped. As applications, the
invariant best simultaneous approximation results are proved.
