Closed-Form Associators in Permutative Chord Diagrams
Peter Lee
Construction of a universal finite-type invariant can be reduced, under suitable assumptions, to the solution of certain equations (the hexagon and pentagon equations) in a particu…
On the Action of the Symmetric Group on the Cohomology of Groups Related to (Virtual) Braids
Peter Lee
In this paper we consider the cohomology of four groups related to the virtual braids of [Kauffman] and [Goussarov-Polyak-Viro], namely the pure and non-pure virtual braid groups (…
The Pure Virtual Braid Group Is Quadratic
Peter Lee
If an augmented algebra K over Q is filtered by powers of its augmentation ideal I, the associated graded algebra grK need not in general be quadratic: although it is generated in…
A Note on Cubic Interactions in PP-Wave Light Cone String Field Theory
Peter Lee, Sanefumi Moriyama, Jongwon Park
We study the string modes in the pp-wave light-cone string field theory. First, we clarify the discrepancy between the Neumann coefficients for the supergravity vertex and the zero…
Cubic Interactions in PP-Wave Light Cone String Field Theory
Peter Lee, Sanefumi Moriyama, Jongwon Park
We use the supergravity modes to clarify the role of the prefactor in the light-cone superstring field theory on PP-wave background. We verify some of the proposals of the recent p…
Open Strings in PP-Wave Background from Defect Conformal Field Theory
Peter Lee, Jongwon Park
We consider open strings ending on a D5-brane in the pp-wave background, which is realized in the Penrose limit of with an brane. A complete li…
