New Exact Solutions Of High-dimensional Fractional Nonlinear Partial Differential Equations

It is very important and interesting to construct exact solutions of nonlinear partial differential equation.In this paper,The exact solution-s of(3+1)-dimensional space-time fractional mKdV-ZK equation,Density-dependent fractional DR equation with quadratic nonlinearity and(3+1)-dimensional KdV equation are constructed by using extended(G'/G)-expansion method and the conformable fractional derivative.Thus more richer new solutions are ob-tained,those new solutions include hyperbolic function solutions with parameters,trigonometric function solutions,rational function solutions.
