Geometric configurations, regular subalgebras of E10 and M-theory cosmology
(IOP Publishing, 2006-12)
We re-examine previously found cosmological solutions to eleven-dimensional supergravity in the light of the E10-approach to M-theory. We focus on the solutions with non zero electric field determined by geometric ...
RG study of a non-local sine-Gordon model
(Elsevier Science, 2003-07)
We study a non-local version of the sine-Gordon model connected to a many-body system with backward and umklapp scattering processes. Using renormalization group methods we derive the flow equations for the couplings and ...
