    A technique is given to generate coupled scalar field solutions in colliding Einstein-Maxwell (EM) waves. By employing the Bell-Szekeres solution as seed and depending on the chosen scalar field, it is possible to construct ...
  • A New Solution of the Deep Bed Filtration 
    Saatçı, A.M.; Halilsoy, Mustafa (The Chemical Engineering Journal, 1987)
    We present a more general solution of the standard deep bed filtration equations which explains the initial improvement of effluent quality as a suspension passes through a porous medium. Our solution gives a good ...
  • Nonsingular colliding wave solutions in Einstein-Maxwell-dilaton-axion theory E. Halilsoy and M. Ha 
    Halilsoy, Elif; Halilsoy, Mustafa (Physical Review D, American Physical Society (APS), 2004)
    The local isometry between black holes and colliding plane waves is employed to derive new colliding wave solutions in the Einstein-Maxwell-dilaton-axion theory. The technique is applied to the asymptotically nonflat linear ...
  • Note on: "Domain wall universe in the Einstein--Born--Infeld theory" Phys. Lett. B 679 (2009) 160 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (Physics Letters B, Elsevier, 2011)
    The interaction between bulk and dynamic domain wall in the presence of a linear / non-linear electromagnetism make energy density, tension and pressure on the wall all variables, depending on the wall position. In [1] ...
  • Note on ‘‘Large family of colliding waves in the Einstein–Maxwell theory’’ 
    Halilsoy, Mustafa (Journal of Mathematical Physics, American Isntitute of Physics (AIP), 1993)
    As a supplementary to the general class of solutions published in this journal [J. Math. Phys. 31, 2694 (1990)] we remark that for a specific choice of our seed function we obtain an interesting solution which reduces ...
  • On a Class Transcendent Solution in EM Theory 
    Halilsoy, Mustafa (Europhysics Letters EPL, Institute of Physics (IOP) Publishing, 1986)
    The role of the Bavinonic condition in a previously obtained solution of the Ernst equation is clarified.
  • On Some Properties of the NUT-Curzon Space-Time 
    Halilsoy, Mustafa; Gürtuğ, Özay (Nuovo Cimento B, Springer, 1994)
    We present the NUT generalization of the Curzon metric with its multipole extension. The Schwarzschild quadrupole potential in the prolate spheroidal coordinates turns out to cancel the quadrupole moment of a ...

    Halilsoy, Mustafa (General Relativity and Gravitation, Springer, 1983)
    We make an alternative approach to Bonnorification by making use of effective Lagrangians for the gravitational fields. Using this technique we obtain a new Einstein-Maxwell solution
