Optimal competitive online ray search with an error-prone robot
Tom Kamphans, Elmar Langetepe
We consider the problem of finding a door along a wall with a blind robot that neither knows the distance to the door nor the direction towards of the door. This problem can be sol…
Approximating the first -betti number of residually finite groups
W. Lück, D. Osin
We show that the first -betti number of a finitely generated residually finite group can be estimated from below by using ordinary first betti numbers of finite index normal s…
Uniqueness of normalized homeomorphic solutions to nonlinear Beltrami equations
Kari Astala, Albert Clop, Daniel Faraco +2
We settle the problem of the uniqueness of normalized homeomorphic solutions to nonlinear Beltrami equations . It turns out that the uniquene…
Approximating Vertex Cover in Dense Hypergraphs
Jean Cardinal, Marek Karpinski, Richard Schmied +1
We consider the minimum vertex cover problem in hypergraphs in which every hyperedge has size k (also known as minimum hitting set problem, or minimum set cover with element freque…
Time-Integrated Searches for Point-like Sources of Neutrinos with the 40-String IceCube Detector
The IceCube Collaboration, R. Abbasi
We present the results of time-integrated searches for astrophysical neutrino sources in both the northern and southern skies. Data were collected using the partially-completed Ice…
The K-theoretic Farrell-Jones conjecture for CAT(0)-groups
Christian Wegner
We prove the K-theoretic Farrell-Jones conjecture with (twisted) coefficients for CAT(0)-groups.
