Dromion and other exact solutions of (2+1)-dimensional Broer–Kaup equation

Using homogenous balance method we obtain Bäcklund transformation and a linear partial differential equation of Broer–Kaup (BK) equation. As a result, multisoliton and single soliton and other exact solutions of (2+1)-dimensional BK equation are given. By analyzing single soliton solution, we get some dromions solutions.
