Einstein-Yang-Mills fields immune to quantum corrections
Martin Kuchynka
Just recently, the class of all Einstein-Maxwell fields solving simultaneously also any higher-order modification of the Eintein-Maxwell theory has been completely identified. In t…
Gauge fields with vanishing scalar invariants
Martin Kuchynka
We consider extension of some established techniques of study of tensor fields on Lorentzian manifolds of arbitrary dimension to non-Abelian gauge covariant fields. These are then…
Einstein-Maxwell fields with vanishing higher-order corrections
Martin Kuchynka, Marcello Ortaggio
We obtain a full characterization of Einstein-Maxwell -form solutions in -dimensions for which all higher-order corrections vanish identical…
Almost universal spacetimes in higher-order gravity theories
Martin Kuchynka, Tomáš Málek, Vojtěch Pravda +1
We study almost universal spacetimes - spacetimes for which the field equations of any generalized gravity with the Lagrangian constructed from the metric, the Riemann tensor and i…
Weyl type N solutions with null electromagnetic fields in the Einstein-Maxwell -form theory
Martin Kuchynka, Alena Pravdova
We consider -dimensional solutions to the electrovacuum Einstein-Maxwell equations with the Weyl tensor of type N and a null Maxwell -form field. We prove that such space…
