Perturbative Quantum Field Theory and Homotopy Algebras

21 Aug 2020 Jurco Branislav Kim Hyungrok Macrelli Tommaso Saemann Christian Wolf Martin

We review the homotopy algebraic perspective on perturbative quantum field theory: classical field theories correspond to homotopy algebras such as $A_\infty$- and $L_\infty$-algebras. Furthermore, their scattering amplitudes are encoded in minimal models of these homotopy algebras at tree level and their quantum relatives at loop level... (read more)
