Points of Upper Local Uniform Monotonicity in Calderón-Lozanovskii Spaces

We start with some results concerning ULUM and UM points in general Köthe sequence spaces. Next we present full characterization of ULUM points in Calderón-Lozanovskii spaces. In particular, we obtain the respective criteria for ULUM points in Orlicz-Lorentz spaces and Orlicz spaces.
