The double shuffle, or dimorphic, relations satisfied by elements of the Lie algebra <span>(scriptstyle {{mathfrak {ds}}})</span> express two families of algebraic relations between multiple zeta values that conjecturally generate all relations. In analogy with this, elements of the elliptic double shuffle Lie algebra <span>(scriptstyle {{mathfrak {ds}}_{ell}})</span> are Lie polynomials having a dimorphic property called <span>(scriptstyle {Delta })</span>-bialternality that conjecturally describes the (dual of the) set of algebraic relations between <i>elliptic multiple zeta values</i>, which arise as coefficients of a certain elliptic generating series (constructed explicitly in Lochak et al.\u0000[15]) in On elliptic multiple zeta values 2016, in preparation) and closely related to the elliptic associator defined by Enriquez\u0000[10].
