Abstract: The well-known Kalton’s theorem characterizes weakly convergent sequences in the space of compact linear operators on Banach spaces. In this talk, we give new versions of Kalton’s theorem for weakly convergent sequences in the space of compact regular linear operators on Banach lattices and in the space of regular homogeneous polynomials on Banach lattices. As applications, we obtain sufficient conditions for the reflexivity of the space of regular linear operators and the space ofregular homogeneous polynomials on Banach lattices. We show that these sufficient conditions are also necessary under the assumption of the bounded regular approximation property. We also show that under some conditions, the reflexivity of , the Banach space of all bounded linear operators from to , implies the reflexivity of , the Banach lattice of all regular linear operators from to . However, the converse is not true by constructing an interesting example.
