| Mar 20, 2014 at 22:02 | comment | added | Nathaniel Johnston | Can you be more clear about what you mean by "other cases"? If you are only allowed to consider $M$ and $N$, then the conditions you listed are optimal (i.e., the numerical range can be non-convex for all other choices of $M,N$). So do you want conditions on the $A_i$'s instead? | |
