"... Polchinski and Pouliot have shown that Mmomentum transfer between membranes in supergravity can be understood as a nonperturbative instanton effect in gauge theory. Here we consider a dual process: electric flux transmission between Dbranes. We show that this process can be described in perturbat ..."

Perturbative gauge theory as a string theory in twistor space
 Commun. Math. Phys
"... Perturbative scattering amplitudes in YangMills theory have many unexpected properties, such as holomorphy of the maximally helicity violating amplitudes. To interpret these results, we Fourier transform the scattering amplitudes from momentum space to twistor space, and argue that the transformed ..."

Particle Hamiltonian and Perturbative Gauge Theories
, 1994
"... We discuss the Hamiltonian formulation of the Schwinger propertime method of calculating Green functions in gauge theories. Instead of calculating Feynman diagrams, we solve the corresponding DysonSchwinger equations. We express the solutions in terms of vertex operators, which consist of the zero ..."

Perturbative gauge theory in a background
, 2007
"... Abstract: Motivated by the gluon condensate in QCD we study the perturbative expansion of a gauge theory in the presence of gauge bosons of vanishing momentum, in the specific case of an abelian theory. The background is characterised by a dimensionful parameter Λ affecting only the onshell prescri ..."

Perturbative gauge theory and closed string tachyons
 JHEP
, 2005
"... We find an interesting connection between perturbative large N gauge theory and closed superstrings. The gauge theory in question is found on N D3branes placed at the tip of the cone R 6 /Γ. In our previous work we showed that, when the orbifold group Γ breaks all supersymmetry, then typically the ..."

Gribov's Horizon  A Vista On NonPerturbative Gauge Theory
"... Introduction Volodja Gribov was a lightning and thundering example of scientific integrity and honesty. The first time I heard him speak was at a meeting in Eger in August 1988. My first interactions with him stem from a visit to my friends here in Minneapolis in May of 1995. At that time I gave tw ..."

two talks, both on the global issue of gauge fixing and its applications to the dynamics in gauge theories. I did get to the end of those talks and had a few private discussions with Volodya. It is not that I believe to have convinced him this was the way to go  our results are furthermore only very
hepth/0108006 Probing Black Holes in NonPerturbative Gauge Theory
, 2001
"... We use a 0brane to probe a tendimensional nearextremal black hole with N units of 0brane charge. We work directly in the dual stronglycoupled quantum mechanics, using meanfield methods to describe the black hole background nonperturbatively. We obtain the distribution of W boson masses, and f ..."

ChernSimons Gauge Theory as a String Theory
, 2003
"... Certain two dimensional topological field theories can be interpreted as string theory backgrounds in which the usual decoupling of ghosts and matter does not hold. Like ordinary string models, these can sometimes be given spacetime interpretations. For instance, threedimensional ChernSimons gaug ..."

Simons gauge theory can arise as a string theory. The worldsheet model in this case involves a topological sigma model. Instanton contributions to the sigma model give rise to Wilson line insertions in the spacetime ChernSimons theory. A certain holomorphic analog of ChernSimons theory can also arise as a
ANLHEPPR01016 hepth/0103132 Massive selfdual perturbed gauge theory
, 2001
"... Spontaneously broken gauge theories are described as a perturbation of selfdual gauge theory. Instead of the incorporation of scalar degrees of freedom, the massive component of the gauge field is obtained from an antiselfdual field strength consisting of three components before gauge fixing. The i ..."
