Vortex induced confinement and the KugoOjima confinement criterion
"... Abstract. The SU(2) YangMills gluon and ghost Greenfunctions are studied in Landau gauge by means of lattice gauge simulations. A focal point is their low energy behavior since in particular the KugoOjima confinement criterion relates a diverging ghost form factor at vanishing momentum transfer t ..."

NUMERICAL TESTS OF THE KUGOOJIMA COLOR CONFINEMENT CRITERION
, 2000
"... The KugoOjima color confinement criterion, which is based on the BRST symmetry of QCD is numerically tested by the lattice Landau gauge simulation. We first discuss the BRST symmetry on the lattice and the Gribov copy problem. The horizon function defined by Zwanziger based on the Ulinear definiti ..."

A confinement criterion for securely executing mobile code
"... Mobile programs, like applets, are not only ubiquitous, but also potentially malicious. We study the case where mobile programs are executed by a host system in a secured environment, in order to control all accesses from mobile programs to local resources. The article deals with the following quest ..."

question: how to ensure that the local environment is secure? We answer by giving a confinement criterion: if the type of the local environment satisfies it, then no mobile program can directly access to a local resource. The criterion, which is typebased and hence decidable, is valid for a functional
The Kugo–Ojima confinement criterion and the Infrared Behavior of Landau gauge QCD ∗
, 2008
"... Recent investigations of the Dyson–Schwinger equations and Monte– Carlo lattice calculations resulted in a coherent description of the fully dressed gluon, ghost and quark propagators in Landau gauge QCD. In the Dyson–Schwinger approach the infrared behaviour of these propagators is determined analy ..."

verification of the Kugo–Ojima confinement criterion. Our numerical analysis clearly reveals positivity violation for the gluon propagator generated by a cut in the complex momentum plane. The nonperturbative strong running coupling resulting from these propagators possesses an infrared fixed point. The quark
1 Test of the KugoOjima Confinement Criterion in the Lattice Landau Gauge
, 1999
"... We present the first results of numerical test of the KugoOjima confinement criterion in the lattice Landau gauge. The KugoOjima criterion of colour confinement in the BRS formulation of the continuum gauge theory is given by u a b(0) = −δ a b, where dxe ip(x−y) 〈0TDµc a (x)g(Aν × ¯c) b (y)0 〉 ..."

A test of the KugoOjima confinement criterion by lattice Landau gauge QCD simulations
, 2000
"... The first test of the KugoOjima colour confinement criterion by the lattice Landau gauge QCD simulation is performed. The parameter u which is expected to be −1δ a b in the continuum theory was found to be −0.7δ a b in the strong coupling region. The data is analysed in connection with the theory o ..."
