= Bäcklund transform
{wiki=Bäcklund_transform}
The Bäcklund transform is a method used in the field of differential equations, particularly in the theory of integrable systems. It is named after Swedish mathematician Lars Bäcklund, who introduced it in the context of generating new solutions from known ones for certain types of partial differential equations (PDEs). The Bäcklund transform has several important features: 1. **Generation of Solutions**: It allows for the construction of new solutions from existing ones.
