From the Choi Formalism in Infinite Dimensions to Unique Decompositions of Generators of Completely Positive Dynamical Semigroups
Frederik vom Ende
Given any separable complex Hilbert space, any trace-class operator which does not have purely imaginary trace, and any generator of a norm-continuous one-parameter semigro…
Von Neumann Type of Trace Inequalities for Schatten-Class Operators
Gunther Dirr, Frederik vom Ende
We generalize von Neumann's well-known trace inequality, as well as related eigenvalue inequalities for hermitian matrices, to Schatten-class operators between complex Hilbert spac…
The C-Numerical Range for Schatten-Class Operators
Gunther Dirr, Frederik vom Ende
We generalize the -numerical range from trace-class to Schatten-class operators, i.e. to and with $1/p + 1…
The C-Numerical Range in Infinite Dimensions
Gunther Dirr, Frederik vom Ende
In infinite dimensions and on the level of trace-class operators rather than matrices, we show that the closure of the -numerical range is always star-shaped with r…
