Abstract
We characterize finite elements, an order-theoretic concept in Archimedean vector lattices, in the setting of ordered Banach spaces with positive unconditional basis as vectors having finite support with respect to their basis representations. Using algebraic vector space bases, we further describe a class of infinite dimensional vector lattices in which each element is finite and even self-majorizing.
