Variation of mass in primordial nucleosynthesis as a test of Induced Matter Brane Gravity
S. Jalalzadeh, A. M. Yazdani
The variation of mass in induced matter theory using Ceroch-Stewart-Walter perturbations of submanifolds [1] is redefined. It is shown that the deviation of primordial Helium produ…
Quantum cosmology with varying speed of light: canonical approach
P. Pedram, S. Jalalzadeh
We investigate --dimensional cosmology with varying speed of light. After solving corresponding Wheeler-DeWitt equation, we obtain exact solutions in both classical and quan…
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…
Noncommutativity, generalized uncertainty principle and FRW cosmology
A. Bina, K. Atazadeh, S. Jalalzadeh
We consider the effects of noncommutativity and the generalized uncertainty principle on the FRW cosmology with a scalar field. We show that, the cosmological constant problem and…
Quantum Stephani exact cosmological solutions and the selection of time variable
P. Pedram, S. Jalalzadeh, S. S. Gousheh
We study perfect fluid Stephani quantum cosmological model. In the present work the Schutz's variational formalism which recovers the notion of time is applied. This gives rise to…
