Abstract of a paper by M. Kandić, M.A.A. Marabeh, V.G. Troitsky
This is an announcement for the paper “Unbounded Norm Topology in Banach Lattices” by M. Kandić<http://arxiv.org/find/math/1/au:+Kandic_M/0/1/0/all/0/1>, M.A.A. Marabeh<http://arxiv.org/find/math/1/au:+Marabeh_M/0/1/0/all/0/1>, V.G. Troitsky<http://arxiv.org/find/math/1/au:+Troitsky_V/0/1/0/all/0/1>. Abstract: A net $(x_{\alpha})$ in a Banach lattice $X$ is said to un-converge to a vector $x$ if $\||x_\alpha-x|\wedge u|\|\rightarrow 0$ for every $u\in X_+$. In this paper, we investigate un-topology, i.e., the topology that corresponds to un-convergence. We show that un-topology agrees with the norm topology iff $X$ has a strong unit. Un-topology is metrizable iff $X$ has a quasi-interior point. Suppose that $X$ is order continuous, then un-topology is locally convex iff $X$ is atomic. An order continuous Banach lattice $X$ is a KB-space iff its closed unit ball $B_X$ is un-complete. For a Banach lattice $X$, $B_X$ is un-compact iff $X$ is an atomic KB-space. We also study un-compact operators and the relationship between un-convergence and weak$^*$-convergence..
