Integrable systems and zero-curvature equations. (Spanish. English summary) Zbl 0696.58020
Summary: We consider the construction of integrable systems analogous to the equations of the Korteweg-de Vries type and others. We analyze the zero- curvature equations in the Lie bialgebra associated to a Yang-Baxter equation. It is shown that those equations may be solved in terms of a Riemannian-Hilbert problem of the appropriate Lie group.
