Cayley-Darboux equation
From Encyclopedia of Mathematics
A third-order partial differential equation that must be necessarily satisfied by a function 
in order for the family of surfaces 
to be complementable to a triply orthogonal system of surfaces. The Cayley–Darboux equation may be written as

where

and
 |
The equation was first obtained in explicit form by A. Cayley [1]. The above form of the equation is due to G. Darboux [2].
