The heterotic G system with reducible characteristic holonomy
Mateo Galdeano, Leander Stecker
We construct solutions to the heterotic G system on almost contact metric manifolds with reduced characteristic holonomy. We focus on --Sasaki manifolds and $(α,δ…
Brane Symmetries Revisited: Symmetries of Tensile and Tensionless Branes in Possibly Degenerate Metrics and their Manifestations
Leron Borsten, Mateo Galdeano, Hyungrok Kim
We analyse the symmetries of tensionless and tensile branes moving in a target space with a possibly degenerate metric, with the worldvolume metric remaining nondegenerate. We reco…
Spin(7)-instantons on Joyce's first examples of compact Spin(7)-manifolds
Mateo Galdeano, Daniel Platt, Yuuji Tanaka +1
We construct -instantons on one of Joyce's compact -manifolds. The underlying compact -manifold given by Joyce is the same as in Lewis' construction of $…
-algebras and strings with torsion
Xenia de la Ossa, Mateo Galdeano, Enrico Marchetto
We explore the connection between super -algebras (-algebras) and -structures with torsion. The former are realised as symmetry algebras of s…
-structures with torsion and the deformed Shatashvili-Vafa vertex algebra
Andoni De Arriba de La Hera, Mateo Galdeano, Mario Garcia-Fernandez
We construct representations of the deformed Shatashvili-Vafa vertex algebra , with parameter , as recently proposed in the physics literature by F…
