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…
Perfect fluid quantum Universe in the presence of negative cosmological constant
P. Pedram, M. Mirzaei, S. Jalalzadeh +1
We present perfect fluid Friedmann-Robertson-Walker quantum cosmological models in the presence of negative cosmological constant. In this work the Schutz's variational formalism i…
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…
Using Spectral Method as an Approximation for Solving Hyperbolic PDEs
P. Pedram, M. Mirzaei, S. S. Gousheh
We demonstrate an application of the spectral method as a numerical approximation for solving Hyperbolic PDEs. In this method a finite basis is used for approximating the solutions…
