Bianchi Type-II Cosmological Model in Presence of Bulk Stress with Varying- in General Relativity
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 1
Abstract
Abstract. Bianchi Type-II space time is investigated in presence of bulk stress given by Landau and Lifshitz . To get a solution, a supplementary condition between metric potentials is used. The viscosity coefficient of bulk viscous fluid is assumed to be a simple power function of mass density where as the coefficient of shear viscosity is consider as proportional to the scale of expansion in the model. The cosmological term Λ(t) is found to be a decreasing function of time, which is supported by results found from recent type Ia supernovae observations. Also some physical and geometrical properties of the model are discussed.

R-Restricted Steiner Problem is NP-Complete
This work aims to arrive a Steiner minimum tree with -terminals. Every full component of a Steiner tree contains almost 4 terminals. In this work, we propose to flash R-restricted Steiner problem which is NP-complete.
