It is the first time that I meet the concept "normal curvature matrix".
By google searching, it seems like a concept in differential geometry. But I know little of differential geometry and do not get any clear definition, properties of it or information on how to calculate it.
Is there any references or ideas on how to understand it?
1)Google books: Google books link
2)Springer book: Springer book link
The content in the second link made me believe this should be a concept in differential geometry.
"normal curvature matrix"
with the quotation marks for google search; I have updated it with the two links I found. $\endgroup$Hessian
which also requires second order derivative information, what is the advantage of using the maximum eigen value of thisnormal curvature matrix
? $\endgroup$
