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] Homotopy-coherent algebra via Segal conditions
H Chu, R Haugseng - Advances in Mathematics, 2021 - Elsevier
Many homotopy-coherent algebraic structures can be described by Segal-type limit
conditions determined by an “algebraic pattern”, by which we mean an∞-category equipped …

[HTML][HTML] Koszul operads governing props and wheeled props
K Stoeckl - Advances in Mathematics, 2024 - Elsevier
In this paper, we construct groupoid coloured operads governing props and wheeled props,
and show they are Koszul. This is accomplished by new biased definitions for (wheeled) …

Koszul duality for operadic categories
M Batanin, M Markl - Compositionality, 2023 - compositionality.episciences.org
Koszul duality is an important ingredient in the theory of algebraic operads. The classical
Koszul duality theory for associative algebras goes a long way back to Priddy [23], but a …

[图书][B] A foundation for PROPs, algebras, and modules
D Yau, MW Johnson - 2015 - books.google.com
PROPs and their variants are extremely general and powerful machines that encode
operations with multiple inputs and multiple outputs. In this respect PROPs can be viewed as …

[图书][B] On operads, bimodules and analytic functors
N Gambino, A Joyal - 2017 - ams.org
We develop further the theory of operads and analytic functors. In particular, we introduce
the bicategory $\operatorname {OpdBim} _ {\mathcal {V}} $ of operad bimodules, that has …

Operadic categories as a natural environment for Koszul duality
M Batanin, M Markl - Compositionality, 2023 - compositionality.episciences.org
Operads are a powerful foundation for handling composition and substitution of various
structures. While at first the underlying combinatorics of operads concerned how trees are …

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 …

Moment categories and operads
C Berger - arXiv preprint arXiv:2102.00634, 2021 - arxiv.org
A moment category is endowed with a distinguished set of split idempotents, called
moments, which can be transported along morphisms. Equivalently, a moment category is a …

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 …
