The scalarized Raychaudhuri identity and its applications
Eduard G. Mychelkin, Maxim A. Makukov
We show that the covariant Raychaudhuri identity describing kinematic characteristics of space-time admits a representation involving a geometrical scalar which, depending on c…

Unified geometrical basis for the generalized Ehlers identities and Raychaudhuri equations
Eduard G. Mychelkin, Maxim A. Makukov
It is shown that the timelike, spacelike and null versions of the Ehlers identity, as well as ensuing Raychaudhuri equations, might be all derived within a single geometrical appro…

Antiscalar cosmological background
Eduard G. Mychelkin, Maxim A. Makukov
It is shown that the antiscalar approach to dark energy, whereby the energy-momentum tensor of the scalar field has the sign opposite to that of the rest of the matter, follows fro…
