Completion problem of upper triangular $3 \times 3$ operator matrices on arbitrary Banach spaces

Nikola Sarajlija, Dragan S. Djordjević

We solve the completion problem of $3 \times 3$ upper triangular operator matrix acting on a direct sum of Banach spaces and hence generalize the famous result of Han, Lee, Lee (Proc…
