Aug 27, 2013 at 20:02 comment added Tom LaGatta The addition operation on the space of signed measures is really only a partial binary operation, exactly to avoid the issue of $\infty - \infty$. I am not familiar with the work of Giga and Miyakawa, but they probably just avoid the issue entirely. Namely, by considering the triangle inequality $\|x +y\| \le \|x\|+\|y\|$ only when the sum $x+y$ is well-defined.
