Categorical joins

Homological projective duality is a powerful theory developed by
Kuznetsov for studying the derived categories of varieties. It can be
thought of as a categorification of classical projective duality. I
will describe a categorification of the classical join of two
projective varieties, its relation to homological projective duality,
and some applications. This is joint work with Alexander Kuznetsov.
