Abstract
The rigorous construction of quantum Yang-Mills theories, especially in
dimension four, is one of the central open problems of mathematical physics.
Construction of Euclidean Yang-Mills theories is the first step towards this
goal. This article presents a formulation of some of the core aspects this
problem as problems in probability theory. The presentation begins with an
introduction to the basic setup of Euclidean Yang-Mills theories and lattice
gauge theories. This is followed by a discussion of what is meant by a
continuum limit of lattice gauge theories from the point of view of theoretical
physicists. Some of the main issues are then posed as problems in probability.
The article ends with a brief review of the mathematical literature.
