**Recursion operator for the intrinsic generalized sine-Gordon equation**

**Abstract:**

We find the inverse and direct recursion operator for the
intrinsic generalized sine-Gordon equation in any number *n* > 2 of
independent variables. Among the flows generated by the direct operator
we identify a higher-dimensional analogue of the pmKdV equation.
Results have been published in *Fundamental and Applied Mathematics* **12**
(2006), no. 7, 117-128
