Research Activities and Interests: Symbolic
Computation, Triviality
Although officially retired, I expect to remain active for a
number of years to come.
My main research effort for the several years before and
after retirement was spent on software development for symbolic
and scientific computation. That was mostly related to
rewriting Prof. M. Veltman's Schoonschip for a portable, open
software environment, based on Forth and C. In the meantime,
Prof. Jos Vermaseren's Form, an intellectual descendent of
Schoonschip with similar capabilities for large problems, became
available without cost. Since it had also become a tool of
choice among quantum field theorists, I considered myself
scooped.
Because I feel that there is still a useful scope for an
open software implementation of Schoonschip, I might conceivably
take it up again.
My other physics research interests have been getting lower
priority, but I still devote some time to them. It has been
believed for a number of years that φ4 quantum
field theory is trivial (no interaction) in four space-time
dimensions, which applies to the Higgs meson sector of the
standard model. This is a relevant topic, because the presumed
triviality of the Higgs meson shows up in the structure of
low-energy effective field theories, which are nontrivial
because of a cutoff. Several years ago, Baker and Wightman
proposed a mechanism for avoiding the triviality theorems, and
about the same time I found a model that turned out to realize
their mechanism while avoiding a problem they had with the
cluster property. The model led me to an idea on how to extend
Baker and Wightman's mechanism to satisfy the cluster property
and avoid triviality in the general situation. It remains an
interesting question, and my perspective on it is still unusual
and really ought to be pursued. Some questions that are too
hard for analytical analysis ought to be studied with modern
lattice field theory computational methods. At the very least,
my results make it logically inescapable that triviality is
unsettled.
Among several dormant topics on which I have not worked for
awhile, I still have an interest in the point limit of a
classical, relativistic charge.
