If the Yang-Mills theory is the answer, what is the
question?
Abstract. Yang-Mills theories play a central role in modern
physics, forming the basis for the Standard Model (SM) of elementary
particles and forces. The SM has proven to be an exceptionally successful
theory, representing our most sophisticated theoretical framework for
understanding the properties of matter and interactions at the fundamental
level. In technical terms, interactions in the Standard Model are described
by a Yang-Mills theory with the local SU(3)cxSU(2)LxU(1)Y
gauge symmetry. The objective of this article is to explain to
non-physicists, who wish to learn something about contemporary physics, what
this statement means. As the author is not a physicist, this text is intended
as an introduction to Yang-Mills theory for a non-expert audience. However,
given the sophistication of Yang-Mills theory, the paper assumes a fair bit
of mathematical background. It includes some technical details, although
these are largely presented in a superficial manner.
Bornological convergences
Abstract. We study a family of
convergences (actually pretopologies) in the
hyperspace of a metric space
that are generated by covers of the space. This family includes the Attouch-Wets, Fell, and
Hausdorff metric topologies as well as the lower
Vietoris topology.
The unified approach leads to new developments and puts into perspective some
classical results.
