A. Ankiewicz et al., Singularity analysis, balance equations and soliton solution of the nonlocal complex Ginzburg-Landau equation, J ENG MATH, 36(1), 1999, pp. 11-24
The modified complex Ginzburg-Landau equation (mCGLE) which includes a dela
yed response term in the integral form is analysed. In particular, a singul
arity analysis of mCGLE is presented. It is shown that this equation fails
to pass the Painleve test when the non-conservative terms are nonzero. Neve
rtheless, exact solutions to this equation do exist. Stationary solutions c
an be treated using the 'segment balance' method which is an extension of c
onservation laws to non-conservative systems. This method is used to derive
an exact soliton solution of mCGLE.
