Inflation in Higher Dimensional Gauss-Bonnet Cosmology
Isha Pahwa, Debajyoti Choudhury, T. R. Seshadri
A Gauss-Bonnet term naturally appears in the action for gravity when one considers the existence of space time with dimensions more than 1+3. A variety of inflationary models can b…
Late-time acceleration in Higher Dimensional Cosmology
Isha Pahwa, Debajyoti Choudhury, T. R. Seshadri
We investigate late time acceleration of the universe in higher dimensional cosmology. The content in the universe is assumed to exert pressure which is different in the normal and…
Self interacting Brans Dicke cosmology and Quintessence
S. Sen, T. R. Seshadri
Recent cosmological observations reveal that we are living in a flat accelerated expanding universe. In this work we have investigated the nature of the potential compatible with t…
Quintessential Inflation with Dissipative fluid
A. A. Sen, Indrajit Chakrabarty, T. R. Seshadri
We have investigated cosmological models with a self-interacting scalar field and a dissipative matter fluid as the sources of matter. Different variables are expressed in terms of…
