Heat equation mixed boundary conditions

WebDeWitt’s suggestion that the wave function of the universe should vanish at the classical Big Bang singularity is considered here within the framework of one-loop quantum cosmology. For pure gravity at one loop about a flat four-dimensional background bounded by a 3-sphere, three choices of boundary conditions are considered: vanishing of the … WebWe can also consider our problem with the boundary condition (1.2) inverted. Indeed doing the change of variables x W l&x, we will obtain an equivalent problem with the mixed boundary condition at the left-hand side. In this case the function \ will be nondecreasing. The equation (1.1) written as ˝u ˝t + ˝ ˝x {F(u)& ˝u ˝x = =f(t,x)
