标题： Topology and Chiral Symmetry in QCD with Overlap Fermions

摘要： 我们简要回顾了手征规范理论的重叠形式主义、无质量费米子的重叠狄拉克算符及其与域墙费米子的联系。 我们描述了重叠狄拉克算符的性质以及实现它的数值方法。 最后，我们给出了一些使用重叠费米子计算手征对称性破缺和拓扑的例子。 显示英文摘要

摘要： We briefly review the overlap formalism for chiral gauge theories, the overlap Dirac operator for massless fermions and its connection to domain wall fermions. We describe properties of the overlap Dirac operator, and methods to implement it numerically. Finally, we give some examples of quenched calculations of chiral symmetry breaking and topology with overlap fermions.
