Detailed Description

Unpreconditioned Extended-Overlap (N&N) linear operator.

This operator applies the extended version of the hermitian overlap operator Chi = ((1+m_q)/(1-m_q)*gamma_5 + B) . Psi where B is the continued fraction of the pole approx. to eps(H(m))

This operator implements hep-lat/0005004
