A matrix subadditivity inequality for f(A+B) and f(A)+f(B)

Jean-Christophe Bourin, Mitsuru Uchiyama

Let f be a non-negative concave function on the positive half-line. Let A and B be two positive matrices. Then, for all symmetric norms, || f(A+B) || is less than || f(A)+f(B) ||.…

The constraint on the spin dependent structure function $g_{1}$ at low $Q^{2}$ through the sum rule corresponding to the moment at $n = 0$

Susumu Koretune

The sum rules for the spin dependent structure function $g_{1}^{ab}$ in the null-plane formalism corresponding to the moment at $n = 0$ has been transformed to the sum rule which relat…

The sum rule for the polarized structure function $g_{2}$ corresponding to the moment at $n = 0$

Susumu Koretune, Hirofumi Kurokawa

In the small $Q^{2}$ region, the sum rule for the polarized structure function $g_{2}$ corresponding to the moment at $n = 0$ is derived. This sum rule shows that there is a tight connec…
