Cosmological Fluids with Logarithmic Equation of State
S. D. Odintsov, V. K. Oikonomou, A. V. Timoshkin +2
We investigate the cosmological applications of fluids having an equation of state which is the analog to the one related to the isotropic deformation of crystalline solids, that i…

Is a Topology Change After a Big Rip Possible?
V. K. Oikonomou
Motivated by condensed matter physical systems, in which a finite-time singularity indicates that the topology of the system changes, we critically examine the possibility of the U…
