Feynman categories
RM Kaufmann, BC Ward - arXiv preprint arXiv:1312.1269, 2013 - arxiv.org
In this paper we give a new foundational, categorical formulation for operations and
relations and objects parameterizing them. This generalizes and unifies the theory of …

[HTML][HTML] Operadic categories and duoidal Deligne's conjecture
M Batanin, M Markl - Advances in Mathematics, 2015 - Elsevier
The purpose of this paper is two-fold. In Part 1 we introduce a new theory of operadic
categories and their operads. This theory is, in our opinion, of an independent value. In Part …

Homotopy theory of algebras of substitudes and their localisation
We study the category of algebras of substitudes (also known to be equivalent to the regular
patterns of Getzler and operads coloured by a category) equipped with a (semi) model …

[HTML][HTML] Centers and homotopy centers in enriched monoidal categories
M Batanin, M Markl - Advances in Mathematics, 2012 - Elsevier
We consider a theory of centers and homotopy centers of monoids in monoidal categories
which themselves are enriched in duoidal categories. The duoidal categories (introduced by …

The lattice path operad and Hochschild cochains
MA Batanin, C Berger - Contemporary mathematics, 2009 - books.google.com
We introduce two coloured operads in sets–the lattice path operad and a cyclic extension of
it–closely related to iterated loop spaces and to universal operations on cochains. As main …

Bousfield localization and Eilenberg-Moore categories
We prove the equivalence of several hypotheses that have appeared recently in the
literature for studying left Bousfield localization and algebras over a monad. We find …

Regular patterns, substitudes, Feynman categories and operads
We show that the regular patterns of Getzler (2009) form a 2-category biequivalent to the 2-
category of substitudes of Day and Street (2003), and that the Feynman categories of …

Crossed interval groups and operations on the Hochschild cohomology
M Batanin, M Markl - arXiv preprint arXiv:0803.2249, 2014 - ems.press
We prove that the operad B of natural operations on the Hochschild cohomology has the
homotopy type of the operad of singular chains on the little disks operad. To achieve this …

Three Hopf algebras from number theory, physics & topology, and their common background I: operadic & simplicial aspects
We consider three a priori totally different setups for Hopf algebras from number theory,
mathematical physics and algebraic topology. These are the Hopf algebra of Goncharov for …

Cosimplicial monoids and deformation theory of tensor categories
We introduce the notion of n-commutativity (0 Ä n Ä 1) for cosimplicial monoids in a
symmetric monoidal category V, where n D 0 corresponds to just cosimplicial monoids in V …
