Authors’ abstract: We show that on a complex Banach space
, the functions uniformly continuous on the closed unit ball and holomorphic on the open unit ball attaining their norms are dense provided that
has the Radon-Nikodym property. We also show that the same result holds for Banach spaces having the strengthened version of the approximation property but considering just functions with are also weakly uniformly continuous on the unit ball. We prove that there exists a polynomial such that for any fixed positive integer
it cannot be approximated by norm attaining polynomials with degree less than
a predual of a Lorentz sequence space, we prove that the product of two polynomials with degree less than or equal to two attains its norm if, and only if, each polynomial attains its norm.
