ariels
<p>
I've never seen a Hessian in the monastery. Although, if someone asked about identifying local maxima of functions with several variables, it's possible that the matrix
<blockquote><pre>
∂<sup>2</sup>f/∂x<sub>1</sub>∂x<sub>1</sub> ... ∂<sup>2</sup>f/∂x<sub>1</sub>∂x<sub>n</sub><br>
... ... ... ...
∂<sup>2</sup>f/∂x<sub>n</sub>∂x<sub>1</sub> ... ∂<sup>2</sup>f/∂x<sub>n</sub>∂x<sub>n</sub>
</pre></blockquote>
would get mentioned as a way to distinguish minima from maxima.
