The moduli of the universal geometry of heterotic moduli
Jock McOrist, Martin Sticka, Eirik Eik Svanes
We study the moduli of the universal geometry of heterotic vacua. Universal geometry refers to a family of heterotic vacua fibered over the moduli space. The universal…
Recent Developments in Heterotic Moduli
Javier José Murgas Ibarra, Eirik Eik Svanes
We review recent results for heterotic moduli and the Hull--Strominger system. In particular, we discuss mathematical properties of the recently derived deformation operator $\bar…
The decoupling of moduli about the standard embedding
Beatrice Chisamanga, Jock McOrist, Sebastien Picard +1
We study the cohomology of an elliptic differential complex arising from the infinitesimal moduli of heterotic string theory. We compute these cohomology groups at the standard emb…
BPS complexes and Chern--Simons theories from -structures in gauge theory and gravity
Julian Kupka, Charles Strickland-Constable, Eirik Eik Svanes +2
We consider a variety of physical systems in which one has states that can be thought of as generalised instantons. These include Yang--Mills theories on manifolds with a torsion-f…
