Lax representations via twisted extensions of infinite-dimensional Lie algebras: some new results

Abstract: I will discuss the technique for constructing integrable differential equations via twisted extensions of infinite-dimensional Lie algebras. Examples will include a 3D generalization of the Hunter-Saxton equation with the special value of the parameter and the "degenerate heavenly equation".
