Signature change from Schutz's canonical quantum cosmology and its classical analogue
P. Pedram, S. Jalalzadeh
We study the signature change in a perfect fluid Friedmann-Robertson-Walker quantum cosmological model. In this work the Schutz's variational formalism is applied to recover the no…

Quantum FRW cosmological solutions in the presence of Chaplygin gas and perfect fluid
P. Pedram, S. Jalalzadeh
We present a Friedmann-Robertson-Walker quantum cosmological model in the presence of Chaplygin gas and perfect fluid for early and late time epoches. In this work, we consider per…
