New kinks and solitons solutions to the (2+1) -dimensional Konopelchenko–Dubrovsky equation

In this work, the (2+1)-dimensional Konopelchenko–Dubrovsky (KD) equation is studied. The tanh–sech method, the cosh–sinh method and exponential functions method are efficiently employed to handle this equation. By means of these methods, the solitary wave, periodic wave and kink solutions are formally obtained.
