    Tahamtan, Tayebeh (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-06)
    ABSTRACT: Some new exact solutions in a model of f (R) gravity are obtained. Three kinds of matter fields have been used to obtain exact analytic solutions. In the first solution, the Yang-Mills fields are incorporated ...
  • New Metrics for Spinning Spheroids 
    Mustafa, Halilsoy (Journal of Mathematical Physics, American Institute of Physics (AIP), 1992)
    The quaternionic version of the Ernst formalism is used to propose an alternative generalization of the Zipoy-Voorhees metric that represents spinning spheroids. Rotating discs and their superposition that generalize the ...
  • New non-Abelian black hole solutions in Born-Infeld gravity
