Null Energy Condition Violation and Classical Stability in the Bianchi I Metric
Irina Ya. Aref'eva, Nikolay V. Bulatov, Liudmila V. Joukovskaya +1
The stability of isotropic cosmological solutions in the Bianchi I model is considered. We prove that the stability of isotropic solutions in the Bianchi I metric for a positive Hu…
Multifluid Models for Cyclic Cosmology
Irina Aref'eva, Paul H. Frampton, Shinya Matsuzaki
Inspired by the Landau two-fluid model of superfluidity, we consider a similar multifluid description for cosmology where two normal fluids occur for matter and radiation respectiv…
Dynamics in nonlocal linear models in the Friedmann-Robertson-Walker metric
I. Ya. Aref'eva, L. V. Joukovskaya, S. Yu. Vernov
A general class of cosmological models driven by a nonlocal scalar field inspired by the string field theory is studied. Using the fact that the considering linear nonlocal model i…
Stringy Model of Cosmological Dark Energy
Irina Ya. Aref'eva
A string field theory(SFT) nonlocal model of the cosmological dark energy providing w<-1 is briefly surveyed. We summarize recent developments and open problems, as well as point o…
Descent Relations in Cubic Superstring Field Theory
I. Ya. Aref'eva, R. V. Gorbachev, P. B. Medvedev +1
The descent relations between string field theory (SFT) vertices are characteristic relations of the operator formulation of SFT and they provide self-consistency of this theory. T…
Quantization of the Riemann Zeta-Function and Cosmology
I. Ya. Aref'eva, I. V. Volovich
Quantization of the Riemann zeta-function is proposed. We treat the Riemann zeta-function as a symbol of a pseudodifferential operator and study the corresponding classical and qua…
