Why is the Vandermonde determinant harmonic?
It can be checked that the Vandermonde determinant defined as
$$V(\alpha_1, \cdots, \alpha_n) = \prod_{1 \le i < j \le n}(\alpha_i-\alpha_j) $$
is a harmonic function, that is $\Delta V = 0$ where $\ …

Inequality for 0-1 matrices
If you allow the entries of $A$ to be in $\{0, \pm 1\}$ then there is a really nice construction that shows that the sum of the entries of $A^{-1}$ can be exponentially large.
Let the diagonals of $ …
