Title: Higher Algebras in Field Theories

Olaf HOHM (Université de Humboldt, Berlin, Allemagne)

 

Abstract: 

In this talk I will aim to give a pedagogical introduction to
"higher" algebraic structures in physics, notably in (classical and quantum) field theories.
Examples include L-infinity algebras, which generalize the notion of Lie algebras to
structures in which the Jacobi identity can be violated. This violation is then controlled by
"higher brackets". Such structures first emerged in string field theory, but they have
subsequently been shown to be of much wider relevance for general field theories.
