The Nizhnik-Novikov-Veselov system is an isotropic Lax extension of the one-dimensional Korteweg-de Vries equation and the Drinfel’d-Sokolov system is a nonlinear model that possesses some special forms of Lax pairs. Topological kink-type, topological, non-topological, compound topological-non-topological bell-type and singular soliton solutions are successfully constructed. Under the choice of suitable values of parameters, the 2D, 3D and contour graphs to some of the obtained solutions are plotted.</dc:description><dc:publisher>Springer New York LLC</dc:publisher><dc:date>2018</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/3272</dc:identifier><dc:identifier>https://doi.org/10.1007/s11082-018-1406-3</dc:identifier><dc:identifier>0306-8919</dc:identifier><dc:language>en</dc:language><dc:relation>Optical and Quantum Electronics</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/3272</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
