Matrix-convexity of inverse of the cofactor matrix

Matrix-convexity of inverse of the cofactor matrix
Thanks. It arose in proving uniform estimates for an elliptic Monge-Ampere type PDE.

Matrix-convexity of inverse of the cofactor matrix
Indeed. I corrected that.

Geometric mean of two matrices
comment
Geometric mean of two matrices
Thank you. Unfortunately, case 1 is the more problematic one of the two. This is because $K \neq 0$ cannot be $\leq 0$ (its trace is $0$).

$L^p$ stability of the Beltrami equation
comment
$L^p$ stability of the Beltrami equation
Fair enough. Indeed I want them to be uniformly quasiconformal. In fact, stronger than that.
revised
$L^p$ stability of the Beltrami equation
Added an assumption and normalised the quasiconformal maps.
