$D (X) < 1$ or $D^(X) < 1$ imply Property( $K$ )

Tim Dalby

Two new Banach space moduli, that involve weak convergent sequences, are introduced. It is shown that if either one of these moduli are strictly less than 1 then the Banach space h…

Property( $K^{}$ ) Implies $R (X) \leq 1 + \frac{1}{1 + r _{X^{}} ( 1 )}$

Tim Dalby

It is shown that if the dual of a Banach space satisfies Property( $K^{*}$ ) then $R (X) \leq 1 + \frac{1}{1 + r _{X^{*}} ( 1 )} < 2$ where $r_{X^{*}} (c)$ is Opial's…
