We investigate the effectiveness of using smearing as a means to generate a preconditioning transformation for gauge fields prior to fixing to Maximal Centre Gauge. This still leaves the gaugefixed field in the original gauge orbit. As expected, we find that this preconditioning leads to higher maxima of the gauge-fixing condition, resulting in lower numbers of P-vortices. We also find that rem...

Gauge fixing in lattice gauge theory simulations is crucial for many calculations e.g. the study of gauge dependent quantities such as the gluon propagator [1]. However, the standard lattice Landau gauge condition [2] is the same as the continuum condition, ∑ μ ∂μAμ = 0, only to leading order in the lattice spacing, a. The focus of this talk is to use mean-fieldimproved perturbation theory [3] ...

We take the manifestly gauge invariant exact renormalisation group previously used to compute the one-loop β function in SU(N) Yang-Mills without gauge fixing, and generalise it so that it can be renormalised straightforwardly at any loop order. The diagrammatic computational method is developed to cope with general group theory structures, and new methods are introduced to increase its power, ...

We propose a simple and very effective algorithm for solving the generalized assignment problem exactly. Our contribution is twofold: we reformulate the optimization problem into a sequence of decision problems, and we solve these effectively using variable-fixing rules. The decision problems are solved by a simple depth-first lagrangian branch-and-bound method, improved by the variable-fixing ...

field theory with either Zwanziger gauge fixing or, equivalently, Faddeev-Popov Bow-gauge fixing in one higher dimension is presented. Those exact relationships among Green s functions in the stochastically quantized theory are derived by extending suitably Slavnov's method. As a consequence there is no renormalization of the longitudinal part of Green s functions in a =0, to all perturbative o...

With the aims of sharing information about the technical aspects of immunohistochemistry (IHC) and making it possible to make a suitable choice of antibody for histopathological examination, this technical report describes the results of a questionnaire administered during the period of 2014 to 2015 to members of the Conference on Experimental Animal Histopathology. It also describes the immuno...
