A method for solving systems of non-linear differential equations with moving singularities
S. S. Gousheh, H. R. Sepangi, K. Ghafoori-Tabrizi
We present a method for solving a class of initial valued, coupled, non-linear differential equations with `moving singularities' subject to some subsidiary conditions. We show tha…

On signature transition in Robertson-Walker cosmologies
K. Ghafoori-Tabrizi, S. S. Gousheh, H. R. Sepangi
We analyse a classical model of gravitation coupled to a self interacting scalar field. We show that, within the context of this model for Robertson-Walker cosmologies, there exist…
