Numerical evidence for monopoles in 3-dimensional Yang-Mills theory
Recently Anishetty, Majumdar and Sharatchandra have proposed a way of
characterizing topologically non-trivial configurations for 2+1 dimensional
Yang-Mills theory in a local and manifestly gauge invariant manner. In this
paper paper we develop criteria to locate such objects in lattice gauge theory
and find them in numerical simulations.Comment: 6 pages, 4 figures and 2 tables. Revtex. No changes in text. Problem

Noise reduction algorithm for Glueball correlators
We present an error reduction method for obtaining glueball correlators from
monte carlo simulations of SU(3) lattice gauge theory. We explore the scalar
and tensor channels at three different lattice spacings. Using this method we
can follow glueball correlators to temporal separations even up to 1 fermi. We
estimate the improvement over the naive method and compare our results with
existing computations.Comment: 6 pages, 4 tables and 2 figures, computations at larger volumes
