Kundt spacetimes in the Einstein-Gauss-Bonnet theory
Robert Svarc, Jiri Podolsky, Ondrej Hruska
We systematically investigate the complete class of vacuum solutions in the Einstein-Gauss-Bonnet gravity theory which belong to the Kundt family of non-expanding, shear-free and t…
Interpreting A and B-metrics with as gravitational field of a tachyon in (anti-)de Sitter universe
Ondrej Hruska, Jiri Podolsky
We investigate main properties and mutual relations of the so-called A and B-metrics with any value of the cosmological constant. In particular, we explicitly show that both the AI…
Kundt spacetimes in the Gauss-Bonnet Gravity
Ondrej Hruska, Jiri Podolsky
The Gauss-Bonnet gravity is a special case of so-called Quadratic Gravity, which is an extension of Einstein's theory with additional terms in action that are quadratic combination…
Yet another family of diagonal metrics for de Sitter and anti-de Sitter spacetimes
Jiri Podolsky, Ondrej Hruska
In this work we present and analyze a new class of coordinate representations of de Sitter and anti-de Sitter spacetimes for which the metrics are diagonal and (typically) static a…
