A generalization of the Wahlquist solution

摘要

We present a new perfect fluid solution belonging to (1, 1) subfamily of Hauser-Mahlist spaces, rigidly rotating, type D in Petrov classification which reduces to the Wahlquist metric for particular values of our constants of integration. Unfortunately it is characterized by the equation of state of the Wahlquist solution: e + 3p = constant. [References: 18]
