Some remarks on Gopakumar-Vafa invariants
A. Schwarz, I. Shapiro
We show that Gopakumar-Vafa invariants can be expressed in terms of the cohomology ring of moduli space of D-branes without reference to the sl_2 \times sl_2 action. We also give a…
A Friedmann-Lemaitre-Robertson-Walker cosmological model with running Lambda
Ilya L. Shapiro, Joan Sola
The idea of a variable dark energy has been entertained many times in the literature and from many different points of view. Quintessence is just a popular way to implement this id…
A modified Starobinsky's model of inflation: Anomaly-induced inflation, SUSY and graceful exit
Ilya L. Shapiro, Joan Sola
We present a model of inflation based on the anomaly-induced effective action of gravity in the presence of a conformally invariant Hilbert-Einstein term. Our approach is based on…
Vacuum effective action and inflation
J. C. Fabris, A. M. Pelinson, I. L. Shapiro
We consider vacuum quantum effects in the Early Universe, which may lead to inflation. The inflation is a direct consequence of the supposition that, at high energies, all the part…
Torsion: theory and possible observables
Ilya L. Shapiro
We discuss the theoretical basis for the search of the possible experimental manifestations of the torsion field at low energies. First, the quantum field theory in an external gra…
Anomaly-induced effective action for gravity and inflation
J. C. Fabris, A. M. Pelinson, I. L. Shapiro
In the very early Universe the matter may be described by the free radiation, that is by the set of massless fields with negligible interactions between them. Then the dominating q…
