On $n$ -norm preservers and the Aleksandrov conservative $n$ -distance problem

Gy. P. Gehér

The goal of this paper is to point out that the results obtained in the recent papers [7,8,10,11] can be seriously strengthened in the sense that we can significantly relax the ass…

Bilateral weighted shift operators similar to normal operators

György Pál Gehér

We prove that an injective, not necessarily bounded weighted bilateral shift operator on $ℓ^{2} (Z)$ is similar to a normal operator if and only if it is similar to a scal…
