Calculations in THH-Theory

A Telescope Comparison Lemma for Thh

We extend to the non-connective case a lemma of Bökstedt about the equivalence of the telescope with a more complicated homotopy colimit of symmetric spectra used in the construction of THH.

Source Galerkin Calculations in Scalar Field Theory

In this paper, we extend previous work on scalar φ theory using the Source Galerkin method. This approach is based on finding solutions Z[J ] to the lattice functional equations for field theories in the presence of an external source J . Using polynomial expansions for the generating functional Z, we calculate propagators and mass-gaps for a number of systems. These calculations are straightfo...

Glueball Calculations in Large-Nc Gauge Theory

We use the light-front Hamiltonian of transverse lattice gauge theory to compute from first principles the glueball spectrum and light-front wave functions in the leading order of the 1yNc color expansion. We find 0, 2, and 1 glueballs having masses consistent with Nc ­ 3 data available from Euclidean lattice path integral methods. The wave functions exhibit a light-front constituent gluon stru...

New Calculations in Gromov-witten Theory

Multiloop Calculations in Heavy Quark Effective Theory *

We review algorithmic methods for two–loop calculations in HQET, and the analogous methods for on–shell QCD, needed for matching HQET to QCD.
