I was wondering if anyone had any recommendations for Duality Theory. I've touched on Duality before in various courses but it's coming up quite a lot in my studies at the moment.
I guess what I'm after is more of introduction with everything I need kind of in one place. Maybe a topological viewpoint, but I'm not really sure.
Not that it matters but it comes up a lot in microeconomics, so if anyone had any suggestions in regard to that it would be great.
Thanks!
