Homework Statement
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
Homework Equations
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.
