In this paper, we study gravitational collapse in the 5-dimensional Einstein-Gauss-Bonnet (EGB) theory. We construct spherical marginally trapped surfaces and determine their evolution when collapsing matter admits a wide class of initial density distributions. show that location, time formation depend crucially on density, velocity profile matter, as well Gauss-Bonnet (GB) coupling constant. p...

We develop an effective Gauss-Bonnet extension of Loop Quantum Cosmology, by introducing holonomy corrections in modified F (G) theories of gravity. Within the context of our formalism, we provide a perturbative expansion in the critical density, a parameter characteristic of Loop Quantum Gravity theories, and we result in having leading order corrections to the classical F (G) theories of grav...
