Non-linear stability of -corrected Friedmann equations
Heliudson Bernardo, Jan Chojnacki, Vincent Comeau
We study the non-linear stability of fixed-point solutions to the -exact equations from O invariant cosmology, with and without matter perturbations. Previous non-linear…
Clock Fields and Logarithmic Decay of Dark Energy
Robert Brandenberger, Vincent Comeau, Leonardo Fossati +1
We investigate the physical measurability of the infrared instability of a de Sitter phase in the formalism recently proposed by Kitamoto et al.. We find that the logarithmic decay…
Further Results on a Function Relevant for Conformal Blocks
Vincent Comeau, Jean-François Fortin, Witold Skiba
We present further mathematical results on a function appearing in the conformal blocks of four-point correlation functions with arbitrary quasi-primary operators. The -function…
