## Applied Category Theory at UCR – 2017

In 2017 we had a special session on applied category theory at a meeting of
the American Mathematical Society here at U.C. Riverside. You can see
slides of these talks!
There are also videos for some, but these are not
of excellent quality, and some are fragmentary. It will certainly
helpful to download the slides and view those while attempting to
watch these videos.

person whose name is in boldface is the one who gave the talk. Also
check out the 2019 talks.
