Exact Path Integrals by Equivariant Cohomology
Hans Dykstra, Joe Lykken, Eric Raiten
It is a common belief among field theorists that path integrals can be computed exactly only in a limited number of special cases, and that most of these cases are already known. H…

Novel Spin and Statistical Properties of Nonabelian Vortices
Lee Brekke, Hans Dykstra, Adam F. Falk +1
We study the statistics of vortices which appear in (2+1)--dimensional spontaneously broken gauge theories, where a compact group G breaks to a finite nonabelian subgroup H. Two si…

The Marinari-Parisi Model and Collective Field Theory
J. D. Cohn, H. Dykstra
We derive the supersymmetric collective field theory for the Marinari-Parisi model. For a specific choice of the superpotential, to leading order we find a one parameter family of…
