We prove that the mapping class group of a closed oriented surface of genus at least two does not have Kazhdan’s property (T).

We prove that the sequence of projective representations of the mapping class group obtained from the projective flat connection in the SU(n)Verlinde bundles over Teichmüller space is asymptotically faithful, that is the intersection over all levels of the kernels of these representations is trivial, whenever the genus of the underlying surface is at least 3. For the genus 2 case, we prove that...

Attribute Selection Based on FRiS-Compactness

Commonly to classify new object in Data Mining one should estimate its similarity with given classes. Function of Rival Similarity (FRiS) is assigned to calculate quantitative measure of similarity considering a competitive situation. FRiS-function allows constructing new effective algorithms for various Data Mining tasks solving. In particular, it enables to obtain quantitative estimation of c...

Object-orientation has a long tradition at the Computer Science Department, Aarhus University, starting with Simula in the early seventies. For more than 20 years there have been courses in object-oriented programming, including BETA, Smalltalk, Self and others. Recently objectorientation has started to be integrated in other parts of the curriculum such as in software engineering, distributed ...
