The relationships between Invertible Module Maps X and X_z

Yun-Su Kim

If $R$ and $M$ are Hilbert modules (in the sense of R. G. Douglas and V. I. Paulsen), we study the relationship between invertible module maps $X : R \to M$ and $X_{z}:R/R_{z}\to{M/M…

N^p Spaces

Yun-Su Kim

We introduce a new norm, called $N^{p}$ -norm $(1 \leq p < \infty)$ on a space $N^{p} (V, W)$ where $V$ and $W$ are abstract operator spaces. By proving some fundamental properties of t…

C_{0}-Hilbert Modules

Yun-Su Kim

We provide the definition and fundamental properties of algebraic elements with respect to an operator satisfying hypothesis (h). Furthermore, we analyze Hilbert modules using C_0-…

Operator-Valued Norms

Yun-Su Kim

We introduce two kinds of operator-valued norms. One of them is an $L (H)$ -valued norm. The other one is an $L (C (K))$ -valued norm. We characterize the completeness with respect to a…
