“…How to obtain the exact solution of the NPDEs has always been the purpose of researchers. To this day, some effective methods have been proposed to seek for the exact solution of the NPDEs such as the Bäcklund transformation method [7][8][9][10], Cole-Hopf transformation method [11][12][13][14], variational method [15,16], extended rational sinecosine and sinh-cosh methods [17,18], Sardar subequation method [19,20], the Kudryashov approach [21,22], extended sinh-Gordon equation expansion method [23,24], trial equation method [25,26], sub-equation method [27][28][29], Wang's direct mapping method [30], and so on [31][32][33][34][35]. In this work, we aim to study the (3+1)-dimensional B-type Kadomtsev-Petviashvili equation that reads as [36]:…”
