## Solutions of fractional Konopelchenko-Dubrovsky and Nizhnik-Novikov-Veselov equations using a generalized fractional subequation method.(English)Zbl 1470.35401

Summary: A new generalized fractional subequation method based on the relationship of fractional coupled equations is proposed. This method is applied to the space-time fractional coupled Konopelchenko-Dubrovsky equations and Nizhnik-Novikov-Veselov equations. As a result, many exact solutions are obtained including hyperbolic function solutions, trigonometric function solutions, and rational solutions. It is observed that the proposed approach provides a simple and reliable tool for solving many other fractional coupled differential equations.
