Özet

We derive the spectrum of the Dirac operator for the linear sigma model with quarks in the large N-c approximation using renormalization group flow equations. For small eigenvalues, the Banks-Casher relation and the vanishing linear term are recovered. We calculate the coefficient of the next to leading term and investigate the spectrum beyond the low energy regime.
