From Lecture 17:

Is there something mixed up here? From the flow of everything it seems like joins should be meet? And also if \\( \wedge \\) is going to be right adjoint of \\(\Delta\\) shouldn't it go in the opposite direction of \\( \Delta \\) ie. \\( \wedge : A \times A \to A \\)? or am I missing something here?
