The information metric on the moduli space of instantons with global symmetries
In this note we revisit Hitchin's prescription [1] of the Fisher metric as a natural measure on the moduli space of instantons that encodes the space–time symmetries of a classical field theory. Motivated by the idea of the moduli space of supersymmetric

So far we can identify at least three concepts within modern cosmology that bring into debate the question of consciousness in the universe: 1) Fine Tuning; 2) The Anthropic Principle and 3) The Multiverse.

General covariant transition amplitudes in quantum cosmology
The path-integral approach to cosmology consists in the computation of transition amplitudes between states of the quantum geometry of the universe.

Abstract There has been much discussion about the initial conditions of the early Universe in the context of quantum theory. In this paper, we construct the wave function and probability distribution by adopting the quantum version of the BPS equation instead of the usual Wheeler–DeWitt equation in a minisuperspace quantum cosmology with
