Detailed Description

Overlap fermion operator.

This class defines the overlap fermion operator with a given kernel fermion operator that currently is assumed as the Wilson fermion operator. All the necessary parameters for kernel fermion operator must be set outside of the class, while the parameters for the sign function operator are set in this class. When eigenvalues and eigenvectors of the base fermion operator are given, these modes are used in the sign function to improve the approximation formula. 20 Dec 2011 H.Matsufuru YAML is implemented.
