Bounds on the light quark masses
The corrections to the current algebra mass formulae for the pseudoscalar mesons are analyzed by means of a simultaneous exansion in powers of the light quark masses and powers of 1/N. A set of mass formulae is derived, including an inequality, which leads to bounds for ratios of quark masses.

The relative magnitude of the two expansion parameters is related to the mass ratio M η 2 M η′ 2 , which represents a quantity of order N c m s .
