What is Negative Cosmological Constant in Inflation about?

This document discusses how inflation can occur in quantum cosmology even with a negative cosmological constant Λ. It shows that for non-zero Λ, the Wheeler-DeWitt equation has complex solutions at large volumes with two asymptotic regions - one Euclidean anti-de Sitter and one Lorentzian de Sitter. It illustrates this using a minisuperspace model with negative Λ and a scalar field, showing the wave function predicts an ensemble of inflationary universes asymptoting to de Sitter space.
