L-Recursion and a new Logic for Logarithmic Space

Martin Grohe, Berit Grußien, André Hernich +1

We extend first-order logic with counting by a new operator that allows it to formalise a limited form of recursion which can be evaluated in logarithmic space. The resulting logic…

On the difference between the pole and the MSbar masses of the top quark at the electroweak scale

Fred Jegerlehner, Mikhail Yu. Kalmykov, Bernd A. Kniehl

We argue that for a Higgs boson mass M_H ~125 GeV, as suggested by recent Higgs searches at the LHC, the inclusion of electroweak radiative corrections in the relationship between…

When Nonlocal Coupling Between Oscillators Becomes Stronger: Patched Synchrony or Multi-Chimera States

Iryna Omelchenko, Oleh E. Omel'chenko, Philipp Hövel +1

Systems of nonlocally coupled oscillators can exhibit complex spatio-temporal patterns, called chimera states, which consist of coexisting domains of spatially coherent (synchroniz…
