The First Integral Method for (3+1) dimensional modified KdV-Zakharov-Kuznetsov and Hirota equations Mustafa Inc, Bulent Kılıç and Yavuz Uğurlu minc@firat.edu.tr Firat University, Elazığ We use first integral method to find traveling wave solutions of (3+1) dimensional modified KdV-Zakharov-Kuznetsov and Hirota equations in this paper. This method is based on commutative algebra. This is effective method for finding solutions of nonlinear partial differential equations. Keywords: First integral method, (3+1) dimensional modified KdV-Zakharov-Kuznetsov equation, Hirota equation, traveling wave solutions. References [1] Parkes, E. J., Duffy, B.
