I was wondering what exactly the difference between a regular (proper? is that the term) hessian is and a bordered hessian. It is difficult to find material in the book or online at this point. I mean mathmatically so that were i to do a problem i would know the layout and what differs between the two. At this point I am aware that a bordered hessian is for constrained optimizations and a proper hessian for unconstrained from there i am unaware where they differ. Theoretically and forumlaically how do they differ?

At this point i think it is something like

2. Relevant equations

3. The attempt at a solution

Proper Hessian

lZxx Zxyl

lZyx Zyyl

Then you find the determinant

A bordered hessian would be

l 0 Fx Fy l

l Fx Zxx Zxy l

l Fy Zyx Zyy l

Is that right because it seems too simple.
