Isolated critical point from Lovelock gravity
Brian P. Dolan, Anna Kostouki, David Kubiznak +1
For any K(=2k+1)th-order Lovelock gravity with fine-tuned Lovelock couplings, we demonstrate the existence of a special isolated critical point characterized by non-standard critic…
Tachyon - Dilaton driven Inflation as an alpha' - non-perturbative solution in First Quantized String Cosmology
Anna Kostouki
Applying a novel non-perturbative functional method framework to a two-dimensional bosonic sigma model with tachyon, dilaton and graviton backgrounds we construct exact (non pertur…
Tachyon-Dilaton-induced Inflation as an alpha'-resummed String Background
Jean Alexandre, Anna Kostouki, Nick E. Mavromatos
Within the framework of a novel functional method on the world-sheet of the string, we discuss simple but re-summed (in the Regge slope) inflationary scenarios in the context of cl…
Non-renormalization for the Liouville wave function
J. Alexandre, Anna Kostouki, N. E. Mavromatos
Using an exact functional method, within the framework of the gradient expansion for the Liouville effective action, we show that the kinetic term for the Liouville field is not re…
