Q: Are the determinants of these matrices always negative under these conditions?

BAYMAXSuppose $A,B \in M_{n}(\Bbb{R})$ such that $A = \left[C_{1}\middle|\frac{I}{0\dots0}\right], B= \left[C_{2}\middle|\frac{I}{0\dots0}\right]$ , where $A$ and $B$ have different first columns (represented as $C_{1}, C_{2}$). Let $\lambda_{i}, i=1, \ldots, n$ denote the eigenvalues of $AB^2$. Then ...

I think more researchers might see it there

Q: Should we burninate the [customer] tag?

Daniel Widdis This tag is in phase 2 of the burnination process described here. The question and comments have been cleaned to allow for on-topic discussion about the burnination of this tag. Please keep it that way. If you want to discuss the process of burnination itself, post a new question on Meta or vis...
