Symmetries of the Chern-Simons Theory in the Axial Gauge, Manifold with Boundary
The field equations of the Chern-Simons theory quantized in the axial gauge
are shown to be completely determined by supersymmetry Ward identities which
express the invariance of the theory under the topological supersymmetry of
Delduc, Gieres and Sorella together with the usual Slavnov identity without
requiring any action principle.Comment: 8 pages LaTeX, report UGVA-DPT 1994/01-84
Local Electronic Structure and High Temperature Superconductivity
It is argued that a new mechanism and many-body theory of superconductivity
are required for doped correlated insulators. Here we review the essential
features of and the experimental support for such a theory, in which the
physics is driven by the kinetic energy.Comment: 8 Pages Latex. For the Proceedings of HTS99, Miami, FL, Jan. 199
Five-Dimensional BF Theory and Four-Dimensional Current Algebra
We consider the relation between the five-dimensional BF model and a
four-dimensional local current algebra from the point of view of perturbative
local quantum field theory. We use an axial gauge fixing procedure and show
that it allows for a well defined theory which actually can be solved exactly.Comment: 15 pages LaTeX file +3 Figures in TexDraw (available from hep-th)

Exact Results for 1D Kondo Lattice from Bosonization
We find a solvable limit to the problem of the 1D electron gas interacting
with a lattice of Kondo scattering centers. In this limit, we present exact
results for the problems of incommensurate filling, commensurate filling,
impurity vacancy states, and the commensurate-incommensurate transition.Comment: 4 pages, two columns, Latex fil
Stripe phases in high-temperature superconductors
Stripe phases are predicted and observed to occur in a class of
strongly-correlated materials describable as doped antiferromagnets, of which
the copper-oxide superconductors are the most prominent representative. The
existence of stripe correlations necessitates the development of new principles
for describing charge transport, and especially superconductivity, in these
materials.Comment: 5 pp, 1 color eps fig., to appear as a Perspective in Proc. Natl.

The three-dimensional BF Model with Cosmological Term in the Axial Gauge
We quantize the three-dimensional -model using axial gauge conditions.
Exploiting the rich symmetry-structure of the model we show that the
Green-functions correspond to tree graphs and can be obtained as the unique
solution of the Ward-Identities. Furthermore, we will show that the theory can
be uniquely determined by symmetry considerations without the need of an action
principle.Comment: one reference added, transmission errors correcte
