This is what I suspected. Thanks!

comment Evaluate $\int_0^1 \int_\sqrt{y}^1 \int_0^{x^2+y^2} dz dx dy$.
Oh I see, so there is in fact no factor of $3$ that I am missing? The answer is indeed $26/105$?

comment Equality in Minkowski's theorem
What is the bar notation above $g(x)$? I'm a little confused by your exposition on the first paragraph about at least one of the two functions attaining the value 0 or "pointing in the same direction". Are you assuming they are complex-valued?

Is $c \times c$ in your last sentence the counting measure? Do you have any good literature on that?
