Duality Hierarchies and Differential Graded Lie Algebras

Bonezzi, Roberto; Hohm, Olaf

The gauge theories underlying gauged supergravity and exceptional field theory are based on tensor hierarchies: generalizations of Yang-Mills theory utilizing algebraic structures that generalize Lie algebras and, as a ...

Homotopy Transfer and Effective Field Theory I: Tree-level

Arvanitakis, Alex S; Hohm, Olaf; Hull, Chris; Lekeu, Victor

We use the dictionary between general field theories and strongly homotopy algebras to provide an algebraic formulation of the procedure of integrating out of degrees of freedom in terms of homotopy transfer. This includes ...

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory

Arvanitakis, Alex S; Hohm, Olaf; Hull, Chris; Lekeu, Victor

We continue our study of effective field theory via homotopy transfer of -algebras, and apply it to tree-level non-Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable ...

Leibniz Gauge Theories and Infinity Structures

Bonezzi, Roberto; Hohm, Olaf

We formulate gauge theories based on Leibniz(-Loday) algebras and uncover their underlying mathematical structure. Various special cases have been developed in the context of gauged supergravity and exceptional field theory. ...
