The Prophetic Call of Narrative Forms of Theology: Narrative Theology, Asian Tendencies, and Roman Emphases
Julius-Kei Kato challenges the reader to reflect on and uncover the gems of one’s culture (here, specifically Asian) as a source of theology. Asian theologians’ type of narrative theology (the narrating and re-telling of Asians’ experience of faith grounded in their cultures) contributes significantly to the ongoing theological enterprise of the whole Church
Quark confinement due to non-Abelian magnetic monopoles in SU(3) Yang-Mills theory
We present recent results on quark confinement: in SU(3) Yang-Mills theory,
confinement of fundamental quarks is obtained due to the dual Meissner effect
originated from non-Abelian magnetic monopoles defined in a gauge-invariant
way, which is distinct from the well-known Abelian projection scenario. This is
achieved by using a non-Abelian Stokes theorem for the Wilson loop operator and
a new reformulation of the Yang-Mills theory.Comment: 5 pages, 3 eps figures. Talk presented at QCD@Work 2012:

Lattice study of area law for double-winding Wilson loops
We study the double-winding Wilson loops in the SU(N) Yang-Mills theory on
the lattice. We discuss how the area law falloff of the double-winding Wilson
loop average is modified by changing the enclosing contours C1 and C2 for
various values of the number of color N. By using the strong coupling
expansion, we evaluate the double-winding Wilson loop average in the lattice
SU(N) Yang-Mills theory. Moreover, we compute the double-winding Wilson loop
average by lattice Monte Carlo simulations for SU(2) and SU(3). We further
discuss the results from the viewpoint of the Non-Abelian Stokes theorem in the
higher representations.Comment: 8 pages, 7 figures, presented at the 35th International Symposium on
