Category theory is one of the most central parts of mathematics,
a rather formal machinery which is omnipresent in various situations
in relatively distinct more traditional parts of mathematics like algebra,
topology, homotopy theory
or geometry. Some of the popular accounts of the category theory include
Tom Leinster's category theory poster "for politicians"
John Baez's intro about categories, quantization and much more...
and wiki-page on
category theory .

in category theory can be found on
In recent years many more advanced "higher-dimensional" analogues of
categories became very prominent. An interesting web discussion group
on this topic
is the n-category cafe.
An advanced survey of higher categories and operads is written
by Tom Leinster - an arXiv (free) version can be found
Our conference at MedILS will focus on
applications of category theory to geometry, topology, algebra
and mathematical physics
(as well as developments in category theory itself stimulated by
geometrical way of thinking) and will be mainly ignorant, for
coherent focus purposes,
about the extensive connections to formal lingustics,
computer science and logics, the important fields of applications which are
more in focus of numerous other category-theory-related conferences.
