The Grothendieck-Teichmueller Lie algebra and Brown's dihedral moduli spaces
Johan Alm
We prove that the degree zero Hochschild-type cohomology of the homology operad of Francis Brown's dihedral moduli spaces is equal to the Grothendieck-Teichmueller Lie algebra plus…
Brown's dihedral moduli space and freedom of the gravity operad
Johan Alm, Dan Petersen
Francis Brown introduced a partial compactification of the moduli space . We prove that the gravity cooperad, given by the degree-shifted cohomologies of the s…
A universal A-infinity structure on Batalin-Vilkovisky algebras with multiple zeta value coefficients
Johan Alm
We explicitly construct a universal A-infinity deformation of Batalin-Vilkovisky algebras, with all coefficients expressed as rational sums of multiple zeta values. If the Batalin-…
Formal weights in Kontsevich's formality construction and multiple zeta values
Johan Alm
We construct a functor that associates to any dg cooperad of dg commutative algebras (satisfying some conditions) an augmented commutative algebra. When applied to the cohomology o…
Two-colored noncommutative Gerstenhaber formality and infinity Duflo isomorphism
Johan Alm
Using new configuration spaces, we give an explicit construction that extends Kontsevich's Lie-infinity quasi-isomorphism from polyvector fields to Hochschild cochains to a quasi-i…
