摘要：
The time-dependent variable coefficients of Bogoyavlensky-Konopelchenko (BK) equation and generalized Bogoyavlensky-Konopelchenko (gBK) equation are considered in this paper. The integrability test by Painleve analysis is being implemented on both the considered equations. An auto-Backlund transformation has been generated with the help of Painleve analysis for both equations. Auto-Backlund transformation method has been used for obtaining the analytic solutions. By using auto-Backlund transformation method, three different analytic solution families have been derived for each of the considered equations. Multi-soliton solutions are also calculated for both the considered equations by using Hereman and Nuseir algorithm. All the results are expressed graphically in 3D by varying different functions and parametric values. These graphs reveal the physical significance of equations under consideration.
