Possible relationship between initial conditions for inflation and past geodesic incompleteness of the inflationary spacetime
Alexander Kaganovich
According to the Borde-Guth-Vilenkin (BGV) theorem an expanding region of spacetime cannot be extended to the past beyond some boundary . Therefore, the inflationary u…
Possible relationship between initial conditions for inflation and past geodesic incompleteness of the inflationary spacetime
Alexander Kaganovich
According to the Borde-Guth-Vilenkin (BGV) theorem an expanding region of spacetime cannot be extended to the past beyond some boundary \mathcal{B}. Therefore, the inflationary uni…
Mirror-extended standard model with spontaneously broken left-right symmetry and its implementation in the course of cosmological evolution
Alexander B. Kaganovich
A mirror-extended standard model (MESM) is offered, where in the left-right symmetric underlying action the sector of the standard model (SM) and its mirror copy have the same SU(2…
Non-Canonical Volume-Form Formulation of Modified Gravity Theories and Cosmology
David Benisty, Eduardo I. Guendelman, Alexander Kaganovich +2
A concise description is presented of the basic features of the formalism of non-canonical spacetime volume-forms and its application in modified gravity theories and cosmology. Th…
Modified Gravity Theories Based on the Non-Canonical Volume-Form Formalism
David Benisty, Eduardo Guendelman, Alexander Kaganovich +2
We present a concise description of the basic features of gravity-matter models based on the formalism of non-canonical spacetime volume-forms in its two versions: the method of no…
f(R)-Gravity: "Einstein Frame" Lagrangian Formulation, Non-Standard Black Holes and QCD-like Confinement/Deconfinement
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
We consider f(R) = R + R^2 gravity interacting with a dilaton and a special non-standard form of nonlinear electrodynamics containing a square-root of ordinary Maxwell Lagrangian.…
