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.
