A U-statistic estimator for the variance of resampling-based error estimators
Mathias Fuchs, Roman Hornung, Riccardo De Bin +1
We revisit resampling procedures for error estimation in binary classification in terms of U-statistics. In particular, we exploit the fact that the error rate estimator involving…

Equivariant K-homology of Bianchi groups with non-trivial class group
Mathias Fuchs
We compute the equivariant K-homology of the groups PSL_2 of imaginary quadratic integers with trivial and non-trivial class-group. This was done before only for cases of trivial c…

Cyclic Cohomology and Higher Rank Lattices
Mathias Fuchs
We give a new proof of the absence of non-trivial idempotents in the group ring of torsion-free cocompact lattices in SL(n,C). It is based on the following procedure. We lift the c…
