On integrability of a special class of two-component (2+1)-dimensional hydrodynamic-type systems. (English) Zbl 1160.37398
Summary: The particular case of the integrable two component (2+1)-dimensional hydrodynamical type systems, which generalises the so-called Hamiltonian subcase, is considered. The associated system in involution is integrated in a parametric form. A dispersionless Lax formulation is found.
