A cosmological reconstruction of the Higgs vacuum expectation value
Published 2024-12-01“…The coefficient of the quadratic term in the self-interaction potential has an evolution and it leads to a cosmic variation of proton-to-electron mass ratio, $$\mu $$ μ . We perform a cosmological reconstruction from the kinematic parameter jerk and discuss a few cosmological consequences of the theory. …”

The Existence and Effect of Dark Energy Redshift on Cosmological Age
Published 2020-01-01“…A derivation of Cosmological Age explicitly constrained by Cosmic Microwave Background Radiation (CMBR) is presented, demonstrating that the correct value of Cosmological Age is equal to the Hubble Age. …”

Juvenile Cosmology; Or Richard Powers’ Post-Global Doughnut
Published 2010-02-01“…Moving from the Aristotelean to the Einsteinian, Operation Wandering Soul’s terrain is cosmological, while its narrative collapses time/space into an exhibition of something like Richard Feynman’s “sum over the histories” made up of proliferating versions of juvenile massings and vain pilgrimages. …”

Dynamical systems of modified Gauss–Bonnet gravity: cosmological implications
Published 2025-01-01“…The linear perturbations around the fixed points are studied to explore the corresponding stability of points. The cosmological implications are studied in $$f(R,G)=f_0R^nG^{1-n}$$ f ( R , G ) = f 0 R n G 1 - n and $$f(R,G)=f_0R^\alpha +f_1G^\beta $$ f ( R , G ) = f 0 R α + f 1 G β models to identify the qualitative evolution of universe with the flat-FRW spacetime. …”

Fab Four: When John and George Play Gravitation and Cosmology
Published 2012-01-01“…Further generalizations lead to a tensor-scalar theory, dubbed the “Fab Four,” with only first and second order derivatives of the fields in the equations of motion that self-tune to a vanishing cosmological constant. This model needs to be confronted with experimental data in order to constrain its large parameter space. …”
