Killing tensors in foliated spacetimes and photon surfaces
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We discuss a recently proposed geometric method for constructing a nontrivial Killing tensor of rank two in a foliated spacetime of codimension one that lifts trivial Killing tenso…
Killing tensors and photon surfaces in foliated spacetimes
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We present a purely geometric method for constructing a rank two Killing tensor in a spacetime with a codimension one foliation that lifts the trivial Killing tensors from slices t…
Nutty Kaluza-Klein dyons revisited
Igor Bogush, Gérard Clément, Dmitri Gal'tsov +1
We extend the previous analysis of (locally) asymptotically flat solutions of Kaluza-Klein (KK) theory by assuming that the dilaton charge is an independent parameter. This corresp…
Generation of rotating solutions in Einstein-scalar gravity
Igor Bogush, Dmitri Gal'tsov
We revisit the problem of the rotating generalization of the Fisher-Janis-Newman-Winicour solution of the minimal Einstein-scalar theory proving that the two previously proposed so…
