Abstract: We calculate the equivariant index formula for an infinite dimensional Clifford module canonically associated to any Riemannian manifold. It encompasses the fractional index formula of the p...

We explore a new simple N = 2 SQM model describing the motion over complex manifolds in external gauge fields. The nilpotent supercharge Q of the model can be interpreted as a (twisted) exterior holom...

In this paper, it is examined on the half line the inverse problem of scattering theory for a class Dirac operator with discontinuous coefficient and a spectral parameter in the boundary condition . T...

Heat kernel expansion induced action matrix model Dirac operator
2011/3/3
We compute the quantum effective action induced by integrating out fermions in Yang-Mills matrix models on a 4-dimensional background, expanded in powers of a gauge-invariant UV cutoff.

2011/3/2
We consider the effect of discretization errors on the microscopic spectrum of the Wilson Dirac
operator using both chiral Perturbation Theory and chiral Random Matrix Theory. A graded

Effects of dynamical quarks on the spectrum of the Wilson Dirac operator
Effects of dynamical quarks the Wilson Dirac operator
2011/1/7
Effects of dynamical quarks on the microscopic spectrum of the Wilson Dirac operator are analyzed by means of effective field theory. We consider the distributions of the real modes of the Wilson Dira...
A projective Dirac operator on CP^2 within fuzzy geometry
projective Dirac operator fuzzy geometry
2010/12/22
We propose an ansatz for the commutative canonical spin_c Dirac operator on CP^2 in a global geometric approach using the right invariant (left action-) induced vector fields from SU(3). This ansatz ...
The Integrated Density of States for the Wilson Dirac Operator
Integrated Density of States Wilson Dirac Operator
2010/12/3
It is shown that gauge field-dependent fermion Dirac operators from lattice QCD form an ergodic operator family in the probabilistic sense, provided the gauge field is an ergodic random field. As a co...

2010/12/8
We derive a formula for the ¯μ–invariant of a Seifert fibered homology sphere in terms of the –invariant of its Dirac operator. As a consequence, we obtain a vanishing result for the index of ce...
