# A Foundation for PROPs, Algebras, and Modules

Share this page
*Donald Yau; Mark W. Johnson*

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
generalizations of operads that would allow only a single output.
Variants of PROPs are important in several mathematical fields,
including string topology, topological conformal field theory,
homotopical algebra, deformation theory, Poisson geometry, and graph
cohomology. The purpose of this monograph is to develop, in full
technical detail, a unifying object called a generalized PROP. Then
with an appropriate choice of pasting scheme, one recovers (colored
versions of) dioperads, half-PROPs, (wheeled) operads, (wheeled)
properads, and (wheeled) PROPs.

Here the fundamental operation of graph substitution is studied in
complete detail for the first time, including all exceptional edges
and loops as examples of a new definition of wheeled graphs. A notion
of generators and relations is proposed which allows one to build all
of the graphs in a given pasting scheme from a small set of basic
graphs using graph substitution. This provides information at the
level of generalized PROPs, but also at the levels of algebras and of
modules over them. Working in the general context of a symmetric
monoidal category, the theory applies for both topological spaces and
chain complexes in characteristic zero.

This book is useful for all mathematicians and mathematical
physicists who want to learn this new powerful technique.
