On the Triple Pomeron Vertex in Perturbative QCD
, 2002
"... We estimate the size of the triple Pomeron vertex in perturbative QCD and compare with the phenomenological value extracted from Regge fits to experimental data. For simplicity, the results of the QCD analysis are taken in the largeNc limit. We find that the perturbative triple Pomeron coupling is ..."

Perturbative Quantum Field Theory via Vertex Algebras
, 2009
"... In this paper, we explain how perturbative quantum field theory can be formulated in terms of (a version of) vertex algebras. Our starting point is the WilsonZimmermann operator product expansion (OPE). Following ideas of a previous paper [arXiv:0802.2198], we consider a consistency (essentially as ..."

Gluon Condensate and NonPerturbative QuarkPhoton Vertex ∗
, 1999
"... We evaluate the quarkphoton vertex nonperturbatively taking into account the gluon condensate at finite temperature. This vertex is related to the previously derived effective quark propagator by a QED like WardTakahashi identity. The importance of the effective vertex for the dilepton production ..."

Nonperturbative features of the threegluon vertex in
"... We present a calculation of the threegluon vertex from its DysonSchwinger equation in Landaugauge YangMills theory. All tensor structures are considered and backcoupled selfconsistently. Within the chosen truncation, twoloop diagrams as well as diagrams containing Green’s functions beyond t ..."

Optimization of Mesh Locality for Transparent Vertex Caching
"... Bus traffic between the graphics subsystem and memory can become a bottleneck when rendering geometrically complex meshes. In this paper, we investigate the use of vertex caching to transparently reduce geometry bandwidth. Use of an indexed triangle strip representation permits application programs ..."

Perturbations and Vertex Removal in a 3D Delaunay Triangulation
 SODA
, 2003
"... Though Delaunay triangulations are very well known geometric data structures, the problem of the robust removal of a vertex in a threedimensional Delaunay triangulation is still a problem in practice. We propose a simple method that allows to remove any vertex even when the points are in very degen ..."

The Real Topological Vertex at Work
, 2009
"... We develop the real vertex formalism for the computation of the topological string partition function with Dbranes and Oplanes at the fixed point locus of an antiholomorphic involution acting nontrivially on the toric diagram of any local toric CalabiYau manifold. Our results cover in particular ..."

Perturbative constraints on the SlavnovTaylor Identity for the GhostGluon Vertex in QCD
, 1999
"... A recent form of the SlavnovTaylor identity for the ghostgluon vertex of QCD is compared with perturbative results. It is found that this identity, derived assuming ghostghost scattering can be neglected, is not consistent with perturbation theory. A new identity is derived at the oneloop pertur ..."

LOCAL AND NONLOCAL VERTEX CORRECTIONS IN MANYBODY PERTURBATION THEORY
, 2006
"... The GW approximation to ManyBody Perturbation Theory is the leading method for the calculation of excitedstate electronic properties in solids. Methods that go beyond the GW approximation, so called “Vertex Corrections ” have been shown to better describe the bandstructure of solids and have not ..."
