Title: Brackets and cobrackets in topology of surfaces

Abstract: We discuss Lie-type algebraic operations – brackets, cobrackets, and double brackets – in the module generated by free homotopy classes of loops in a surface. This subject was initially inspired by the study of the Atiyah-Bott Poisson brackets on the moduli spaces of surfaces. Recently, the algebraic operations on loops were related to the Kashiwara-Vergne equations on automorphisms of free Lie algebras.
