Combinatorial Deformations of Algebras: Twisting and Perturbations

Gérard Henry Edmond Duchamp, Christophe Tollu, K. A. Penson +1

The framework used to prove the multiplicative law deformation of the algebra of Feynman-Bender diagrams is a \textit{twisted shifted dual law} (in fact, twice). We give here a cle…
