Power mean transforms of operators

Jing-Bin Zhou, Shihai Yang

In this paper, we introduce the power mean transform $P_{I^} » (T)$ of an operator $T$ on a Hilbert space, which is a convex combination of some classical operator transforms such as th…

Mean transforms of unbounded weighted composition operator pairs

Jing-Bin Zhou, Shihai Yang

In this paper, we first characterize the polar decomposition of unbounded weighted composition operator pairs $C_{I ¨ , I ¨ }$ in an $L^{2}$ -space. Based on this characterization…
