Generalized Wronskian solutions for the (3 + 1)-dimensional Jimbo–Miwa equation

More general Wronskian conditions are constructed for the (3 + 1)-dimensional Jimbo–Miwa equation. As a result, the generalized Wronskian solutions including rational solutions, positons, negatons, solitons and interaction solutions are obtained. Moreover, some new solutions, together with some known solutions given by other solving methods, are derived from these Wronskian solutions.
