A nonlinear fractional Sharma–Tasso–Olver equation: New exact solutions

Due to its importance in scientific applications the fractional nonlinear Sharma–Tasso–Olver equation has been studied by several authors from point of view of exact solutions. In this paper, new explicit and exact solutions are obtained by using the fractional complex transform and the improved extended tanh-coth method. The results can be compared with other methods used to solve the same model.
