Schatten-konstruktionen

Algorithmische Konstruktionen von Gittern

I have a great suspicion that for example Euler today would spend much more of his time on writing software because he spent so much of his time e.g., in efforts of calculating tables of moon positions. And I believe that Gauß as well would spend much more time sitting in front of the screen.

Three observations regarding Schatten p classes ∗

The paper contains three results, the common feature of which is that they deal with the Schatten p class. The first is a presentation of a new complemented subspace of Cp in the reflexive range (and p ̸= 2). This construction answers a question of Arazy and Lindestrauss from 1975. The second result relates to tight embeddings of finite dimensional subspaces of Cp in C n p with small n and shows...

Necessary Conditions for Schatten Class Localization Operators

We study time-frequency localization operators of the form A12 a , where a is the symbol of the operator and φ1, φ2 are the analysis and synthesis windows, respectively. It is shown in [3] that a sufficient condition for A12 a ∈ Sp(L(R)), the Schatten class of order p, is that a belongs to the modulation space Mp,∞(R2d) and the window functions to the modulation space M1. Here we prove a partia...

Licht und Schatten - Emotionale Aspekte einer Softwareimplementierung

Entwicklung eines Spieles zum Thema Schatten-IT

Schatten-IT sind Systeme, Organisationsstrukturen oder Prozesse, die Geschäftsprozesse unterstützen, aber weder technisch noch strategisch ins IT-Service-Management integriert sind. Um in Unternehmen ein Bewusstsein für Schatten-IT zu schaffen, wurde ein Lernspiel entwickelt, welches die Facetten von Schatten-IT spielerisch verdeutlichen soll. In diesem Paper wird der Prototyp dieses Spieles vo...
