<p>Is there a specific name for matrices with nonsingular principal submatrices?</p>

<p>"matrices with Gauss decomposition" is the shortest thing that comes to mind. I mean other than $B_-TB_+$.</p>

<p>I've heard them called "strongly nonsingular matrices" in numerical linear algebra. Google that and you'll find some literature.</p>
