followed by dinner at a place to be determined.
"Operads with a Twist of Matrons"
ABSTRACT: In this talk, we’ll review the associative and A_\infty operads
\mathcal{Ass} and \mathcal{A}_\infty and show how they can be used to define an
associative algebra and A_\infty
algebra structure on a module H. We’ll
observe
that Stasheff’s associahedra realize \mathcal{A}_\infty. I’ll conclude
the talk with
a hint of the more general objects \mathcal{H}
and \mathcal{H}_\infty,
called
matrons, which can be used to define bialgebra
and A_\infty bialgebra
structures on H
in a completely analogous way. And I’ll mention that the family of polytopes realizing
\mathcal{H_\infty} includes and
enlarges the family of associahedra.
