Lump solutions of a (2+1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$2+1$$\end{document})-dimensional bSK equation

In this paper, we obtained a kind of lump solutions of (2+1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$2+1$$\end{document})-dimensional bSK equation with the assistance of Mathematica by using the Hirota bilinear method. These lump solutions contain a set of six free parameters. Some contour plots with different determinant values are sequentially made to show that the corresponding lump solutions tend to become zero when the determinant approaches zero. Particularly, the lump solutions with specific values of the included parameters are plotted, as illustrative examples.
