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
