Erwiderung an Hrn. K. H. Meyer

Generalized Frames for B(H, K)

Frames play significant role in various areas of science and engineering. Motivated by the work of Chander Shekhar, S. K. Kaushik and Abas Askarizadeh, Mohammad Ali Dehghan, we introduce the concepts of $K$-frames for $B(mathcal{H, K})$ and  we establish some result. Also, we consider the relationships between $K$-Frames and $K$-Operator Frames for $B(mathcal{H})$.

First order absolute moment of Meyer - K onig

On a theorem of W. Meyer-König and H. Tietz

Let (un) be a sequence of real numbers and let L be an additive limitable method with some property. We prove that if the classical control modulo of the oscillatory behavior of (un) belonging to some class of sequences is a Tauberian condition for L, then convergence or subsequential convergence of (un) out of L is recovered depending on the conditions on the general control modulo of the osci...

Realitätsbezug von Informationsmodellen - Eine Erwiderung auf Kritik

1 Einleitung ROLAND KASCHEK hat in seinem Beitrag „Schwachstellen einer Analyse des Modellbegriffs“ meinen Beitrag „Zum Realitätsbezug von Informationsmodellen“ einer pointierten Kritik unterzogen. Der Stellungnahme zu den einzelnen Kritikpunkten sollen drei Anmerkungen vorangestellt werden. Erstens wird ein kritischer Diskurs zu diesem Thema sehr begrüßt, da das Verständnis von Informationsmod...

An Infinite Family of Gromoll-meyer Spheres

We construct a new infinite family of models of exotic 7-spheres. These models are direct generalizations of the Gromoll-Meyer sphere. From their symmetries, geodesics and submanifolds half of them are closer to the standard 7-sphere than any other known model for an exotic 7-sphere.
