The authors describe a numerical method for the (space-) fractional sine-Gordon equation in one space dimension. Adopting the invariant energy quadratization (IEQ) approach, they modify the equations and create a linearly-implicit method that conserves the modified energy discretely. They also present and analysis of the method as well as some numerical experiments.
