Abstract

In the original language

We study the modified Martinez Alonso-Shabat equation u(y)u(xz) + alpha u(x)u(ty) - (u(z) + alpha u(t))u(xy) = 0 and present its recursion operator and an infinite commuting hierarchy of full-fledged non-local symmetries. To date such hierarchies were found only for very few integrable systems in more than three independent variables.
