    A counterexample of compact operator between Banach lattices

    In this paper we present a counterexample of compact domination compact operator T such that |T'| is compact but |T| need not compact.

    The Order Properties of r–compact Operators on Banach Lattices

    We present here that ℱ(E,F), the space of all r–compact operators from E into F, is a generalised sublattice of ℒ r (E,F) for arbitary Banach lattices E and F, and that the chara...

    Duality properties for b-AM-compact operators on Banach lattices

    We obtain some necessary and some sufficient conditions on Banach lattices E and F for the following conditions to hold: (i) if T: E → F is a b-AM-compact operator, then T′: F′ → E′ is also b-AM-compact operator ...

    Lagrangian methods for optimal control problems governed by a mixed quasi-variational inequality

    This paper studies an optimal control problem where the state of the system is defined by a mixed quasi-variational inequality. Several sufficient conditions for the zero duality gap property between the optim...
