Invitation to operadic dynamics

lie theory open access journals
In 1963, Gerstenhaber invented an operad calculus in the Hochschild complex of an associative algebra; operads were introduced under the name of pre-Lie systems. In the same year, Stasheff constructed quite an original geometrical operad, which nowadays is called an associahedra. The notion of an operad was further formalised by May as a tool for iterated loop spaces. The main principles of the operad calculus (brace algebra) were presented by Gerstenhaber and Voronov. Some quite remarkable research activity in the operad theory and its applications can be observed in the last decade. It may be said that operads are also becoming an important tool for Quantum Field Theory and deformation quantization.
