Abstract

The interaction of solitons with nonlinear point defects is investigated. Analytical solutions are obtained for bright and dark static solitons placed on the defect. The interaction of propagating solitons with nonlinear defects is studied numerically. Depending on the parameters, the solitons can be trapped, transmitted, reflected or split. A comparison with the case of linear defects is made..
