$n$-fold operads in iterated monoidal categories
Forcey, Stefan (Tennessee State University, Nashville)

This presentation explains how the iterated generalization of
braidings and symmetries on a monoidal category allows a highly
structured generalization of the operads that live in one. After a
brief recounting of the meaning of iterated monoidal category, I
introduce a new family tree of simple combinatorial (and pictorial!)
examples. Then I define $n$-fold operads and their algebras, and give
examples which correspond to the just mentioned categories. Finally
there is a discussion of the way that these operads might be helpful in
the description of higher-dimensional weakly enriched iterated monoidal
