With this article, we want to advocate the use of asymptotic methods for the analysis of finite difference schemes. We present several examples to demonstrate the applicability of...
: In this paper, we study spectral versions of the densest subgraph problem and the largest independence subset problem. In the first part, we give an algorithm for identifying sm...
We give some estimates related to nite element multilevel splittings and Sobolev norms of negative order. Basically, results for the positive order case are carried over by dualit...
A class of extended aggregation operators, called impact functions, is proposed and their basic properties are examined. Some important classes of functions like generalized ordere...
We give a short survey of the main principles of our software for the visualisation and animation in mathematics and study the visibility and contour problems in the representation...
