Measures of noncompactness in Hilbert $C^{*}$ -modules

Dragoljub J. Kečkić, Zlatko Lazović

Consider a countably generated Hilbert $C^{*}$ -module $M$ over a $C^{*}$ -algebra $A$ . There is a measure of noncompactness $λ$ defined, roughly as the distance from f…

Measures of noncompactness on the standard Hilbert $C^{*}$ -module

Dragoljub J. Kečkić, Zlatko Lazović

We define a measure of noncompactness $λ$ on the standard Hilbert $C^{*}$ -module $l^{2} (A)$ over a unital $C^{*}$ -algebra, such that $λ (E) = 0$ if and only if $E$ is $A$ -…
