Given \(n\) columns of length \(n+k\), whose first \(n\) rows form a normal matrix, the author studies the possibility of completing them by further \(k\) columns of the same length, to get a normal \((n+k)\times(n+k)\) matrix. This can sometimes be achieved with various additional properties of the lower right \(k\times k\) corner (levels of subnormality).
