Every nonreflexive Banach lattice has the packaging constant equal to 1/2.
Every separable, infinite-dimensional Banach space X has a biorthogonal sequence , with norming on X and bounded, so that, for every x in X and x* in X*, there exists a permutation π(n) of n so that .
We show that every separable complex L₁-predual space X is contractively complemented in the CAR-algebra. As an application we deduce that the open unit ball of X is a bounded homogeneous symmetric domain.
Examples of non-finitely generated function algebras on planar sets with small maximal ideal spaces are given.
It is shown that for every k ∈ ℕ and every spreading sequence eₙₙ that generates a uniformly convex Banach space E, there exists a uniformly convex Banach space admitting eₙₙ as a k+1-iterated spreading model, but not as a k-iterated one.
