    • This situation might be experimentally realized by doping a low spin Ni(III) compound (e.g., YSrNiOsub 4). Moreover, different groups have pointed to the possibility that triplet holes might play a role in cuprate high Tc superconductivity: A. Bianconi et al., Physica C 162 164, 209 (1989);

    • This neglect, although of quantitative significance on short time scales (Ref. 14), should not be important for long wavelengths.
