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…

-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…

-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…

Generalised Einstein metrics on Lie groups

Vicente Cortés, Marco Freibert, Mateo Galdeano

We continue the systematic study of left-invariant generalised Einstein metrics on Lie groups initiated in arXiv:2206.01157. Our approach is based on a new reformulation of the cor…

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 -S…

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 $…

Superconformal algebras for the Schoen Calabi-Yau manifold

Mateo Galdeano

We revisit the proposal of arXiv:2104.05716 for the worldsheet description of string theory compactifications on special holonomy manifolds obtained via connected sums: the geometr…

The Geometry and Superconformal Algebras of String Compactifications with a -structure

Mateo Galdeano

In this thesis we study string compactifications on manifolds equipped with a -structure, placing a special emphasis on the interplay between geometry and physics. We follow two…

Families of solutions of the heterotic G system

Xenia de la Ossa, Mateo Galdeano

We construct new families of solutions of the heterotic G system on squashed homogeneous 3-Sasakian manifolds, that is, using squashed metrics on either the 7-sphere or the Alo…

Superconformal algebras for generalized Spin(7) and G connected sums

Marc-Antoine Fiset, Mateo Galdeano

Worldsheet string theory compactified on exceptional holomony manifolds is revisited following arXiv:1809.06376, where aspects of the chiral symmetry were described for the case wh…
