New periodic soliton solutions for the (3+1)-dimensional potential-YTSF equation

New exact periodic kink-wave, periodic soliton and doubly periodic wave Solutions for the (3 + 1)-dimensional potential-YTSF equation are obtained by using homoclinic test technique, extended homoclinic test technique, two-soliton method and bilinear form method, respectively.
