On quantum information
Adam Paszkiewicz, Tomasz Sobieszek
We investigate the following generalisation of the entropy of quantum measurement. Let H be an infinite-dimensional separable Hilbert space with a 'density' operator ρ, tr ρ=1. Let…
A note on Shannon entropy
Tomasz Sobieszek
We present a somewhat different way of looking on Shannon entropy. This leads to an axiomatisation of Shannon entropy that is essentially equivalent to that of Fadeev. In particula…
A note on interpolation series in the complex domain
Tomasz Sobieszek
Given a convergent sequence of nodes we present a one-dimensional-holomorphic-function version of the Newton interpolation method of polynomials. It also generalises the Taylor and…
Additive Entropies of Partitions
Adam Paszkiewicz, Tomasz Sobieszek
We provide, under minimal continuity assumptions, a description of \textsl{additive partition entropies}. They are real functions on the set of finite partitions that are addit…
Noncontinous additive entropies of partitions
Tomasz Sobieszek
In a previous paper: A. Paszkiewicz, T. Sobieszek, Additive Entropies of Partitions, we have given a description of additive partition entropies that is real functions on the s…
