Order automorphisms of partial isometries in
Fengyang Jia, Guoxing Ji
We investigate and characterize order automorphisms on the set of partial isometries in the finite-dimensional matrix algebra . Different from the classical order…
Star order automorphisms on the poset of type 1 operators
Xinhui Wang, Guoxing Ji
Let be a complex infinite dimensional Hilbert space and the algebra of all bounded linear operators on . The star partial order…
Pencils of pairs of projections
Miaomiao Cui, Guoxing Ji
Let be a self-adjoint operator on a complex Hilbert space . We give a sufficient and necessary condition for to be the pencil of a pair of pro…
Domination by positive weak* Dunford-Pettis operators on Banach lattices
Jin Xi Chen, Zi Li Chen, Guo Xing Ji
Recently, J. H'michane et al. introduced the class of weak* Dunford-Pettis operators on Banach spaces, that is, operators which send weakly compact sets onto limited sets. In this…
Almost Limited Sets in Banach Lattices
Jin Xi Chen, Zi Li Chen, Guo Xing Ji
We introduce and study the class of almost limited sets in Banach lattices, that is, sets on which every disjoint weak null sequence of functionals converges uniformly to zer…
Order continuous extensions of positive compact operators on Banach lattices
Jin Xi Chen, Zi Li Chen, Guo Xing Ji
Let and be Banach lattices. Let be a vector sublattice of and be an order continuous positive compact (resp. weakly compact) operators. We show…
