Almost periodic solutions of a (2+1)(2+1)-dimensional Schwarzian Korteweg de Vries equation

We consider the evolution of the (2+1)(2+1)-dimensional Schwarzian Korteweg de Vries equation View the MathML source{8ϖ2ϖτ+2ϖ2ϖζζη−8ϖϖζϖζη−2ϖϖζζϖη+4ϖζ2ϖη−ϖϖζϖ̃η=0,ϖ2ϖ̃ζ=ϖζ2, Turn MathJax on with ϖ⁄=0ϖ⁄=0 in View the MathML sourceC, while the independent variable ττ (“time”) is complex. We prove that there exist many almost periodic solutions.
