Subexponential Time and Fixed-Parameter Tractability: Exploiting the Miniaturization Mapping
Recently it has been shown that the miniaturization mapping M faithfully translates subexponential parameterized complexity into (unbounded) parameterized complexity. We determine...

Hyperbolic Self-Organizing Maps for Semantic Navigation
We introduce a new type of Self-Organizing Map (SOM) to navigate in the Semantic Space of large text collections. We propose a "hyperbolic SOM" (HSOM) based on a regular...

Impulsive systems triggered by superposed renewal processes
We consider impulsive systems with several reset maps triggered by independent renewal processes, i.e., the intervals between jumps associated with a given reset map are identicall...
