HIGHLIGHTS
- who: Negative-Order Korteweg-de Vries Equation and collaborators from the Institute of Optoelectronic Technology, Lishui University, Lishui, China have published the Article: Nonlocal Symmetry and B¨acklund Transformation of a Negative-Order Korteweg-de Vries Equation, in the Journal: Complexity of 29/Oct/2019
SUMMARY
Olver's concept of a recursion operator for symmetries of an evolution equation was extended to negative powers of the operator, and some negative-order Korteweg-de Vries (nKdV) equations were derived, including the following nKdV equation: ux - vt uxxx + 4ux v + 2uvx Several years later, Lou . . .
