Birla Institute of Technology Hyderabad
Dr. P. K. Sahoo received his M. Sc. (1999), M. Phil. (2000) and Ph. D. (2004) degrees from Sambalpur University, Sambalpur, India. Presently he is working as Assistant Professor in the Department of Mathematics, Birla Institute of Technology & Science-Pilani, Hyderabad Campus, Hyderabad, India. He is the author of about thirty seven research papers in journals of International repute. His main area of research is Cosmology and Relativity. His research addresses the qualitative and quantitative properties of solutions with respect to their local and global behaviour, singularity formation and numerical simulation and investigates the close correspondence between geometrical structures and physical concepts. He has also presented several research papers in National and International Conferences.
The exact solutions of the Einstein field equations for dark energy (DE) in axially symmetric space time under the assumption on the anisotropy of the fluid are obtained for exponential volumetric expansions. The isotropy of the fluid, space and expansion are examined.
