Description
The higher order theories like Lovelock’s and Gauss-Bonnet theories(GB) are unique
as they required no extra field beyond GR and holds the property of field equation for
order not greater than second order. The GB theory arise when order is 2 in Lovelock’s
action. We studied the formation and evolution of the marginally trapped surfaces and
collapsing shell for n-dimension space time during the gravitational collapse of spherical
symmetric dust and viscous fluid matter. We took different density profiles as a initial
data to examine the effect of higher dimension on the formation of marginally trapped
surfaces and collapsing shell in Pure GB gravity.
