#9 as well, the lower limit should be minus infinity.
And #7 is missing a minus sign in the exponent. Otherwise the whole thing diverges.
I actually didn't catch that! That's hilarious.
And the first of #11.
Those are the sourceless Maxwell Equations I'm assuming in vacuum. The divergence of H isn't zero either (divergence of magnetic field strength is) unless the magnetization is divergence-less.
