On bounded module functionals and operators on Hilbert C*-modules without biorthogonally complemented kernels
Michael Frank, Cristian Ivanescu
We investigate the structural reasons behind the existence and non-existence of bounded module functionals and bounded module operators on Hilbert C*-modules whose kernels are not…

Orthogonality-preserving, C*-conformal and conformal module mappings on Hilbert C*-modules
Michael Frank, Alexander S. Mishchenko, Alexander A. Pavlov
We investigate orthonormality-preserving, C*-conformal and conformal module mappings on Hilbert C*-modules to obtain their general structure. Orthogonality-preserving bounded modul…

Strict essential extensions of C*-algebras and Hilbert C*-modules
Michael Frank, Alexander A. Pavlov
In the present paper we develop both ideas of D. Bakić and B. Gulja{š} and the categorical approach to multipliers from E.C. Lance's book and publications of the second author, for…
