WebApr 7, 2024 · Reconstructing the initial conditions of the universe is a key problem in cosmology. Methods based on simulating the forward evolution of the universe have provided a way to infer initial conditions consistent with present-day observations. However, due to the high complexity of the inference problem, these methods either fail to sample a … WebStarting from the general solution (4), we have to choose the c so that the initial condition in (6) is satisﬁed. Substituting t0 into (5) gives us the matrix equation for c : X(t0)c = x0. Since the determinant X(t0) is the value at t0 of the Wronskian of x1 amd x2, it is non-zero since the two solutions are linearly independent (Theorem 5.2C).
