Ginsparg-wilson Relation with R = (aγ 5 D)
نویسنده
چکیده
The Ginsparg-Wilson relation Dγ5 + γ5D = 2aDRγ5D with R = (aγ5D) 2k is discussed. An explicit realization of D is constructed. It is shown that this sequence of topologically-proper lattice Dirac operators tend to a nonlocal operator in the limit k → ∞. This suggests that the locality of a lattice Dirac operator is irrelevant to its index.

The axial anomaly of Ginsparg-Wilson fermion
The axial anomaly of Ginsparg-Wilson fermion operator D is discussed in general for the operator R which enters the chiral symmetry breaking part in the Ginsparg-Wilson relation. The axial anomaly and the index of D as well as the exact realization of the Atiyah-Singer index theorem on the lattice are determined solely by the topological characteristics of the chirally symmetric operator Dc in ...
متن کاملGinsparg-Wilson operators and a no-go theorem
If one uses a general class of Ginsparg-Wilson operators, it is known that CP symmetry is spoiled in chiral gauge theory for a finite lattice spacing and the Majorana fermion is not defined in the presence of chiral symmetric Yukawa couplings. We summarize these properties in the form of a theorem for the general GinspargWilson relation. The Ginsparg-Wilson relation[1] provides a convenient fra...

The role of R in the solutions of the Ginsparg-Wilson relation is discussed. PACS numbers: 11.15.Ha, 11.30.Rd, 11.30.Fs In this note, we would like to clarify some seemingly subtle issues pertaining to the role of R in the solutions of the Ginsparg-Wilson relation [1] Dγ5 + γ5D = 2Dγ5RD . (1) Here R is a positive definite hermitian operator which is local in the position space and trivial in th...
متن کاملAlgebraic Generalization of the Ginsparg-Wilson Relation
A specific algebraic realization of the Ginsparg-Wilson relation in the form γ5(γ5D) + (γ5D)γ5 = 2a (γ5D) 2k+2 is discussed, where k stands for a nonnegative integer and k = 0 corresponds to the commonly discussed Ginsparg-Wilson relation. From a view point of algebra, a characteristic property of our proposal is that we have a closed algebraic relation for one unknown operator D, although this...

We pursue Ginsparg and Wilsons’ block spin approach in the derivation of the Ginsparg-Wilson relation and give a formal argument that the index of the lattice Dirac operator agrees with that of the continuum theory, by identfying unphysical modes of the lattice Dirac operator which do not correspond to any physical modes of the continuum Dirac operator, and by studying the correspondence of the...
