What is it about?
It shows a mathematical way of expressing the eigenvalues of the gravity gradient tensor that allows to give physical meaning to them; it relates the eigenvalues to the curvature of the equipotential surfaces and the nature of the sources.

Why is it important?
It is very important because it allows to understand what eigenvalues mean and to create new interpretation quantities form them.
Perspectives
The eigenvalues of the gravity gradient tensor normally are not interpreted, they are too difficult to understand. I have found a way to understand them and to use some of their parts that constitute them in interpretation. I found that I could define a "modified phase" eigenvalue that is sightly superior and/or easier to interpret than the vertical gravity gradient (the most used interpretation quantity).
