We describe rules for building 2d theories labeled by 4-manifolds. Using the proposed
dictionary between building blocks of 4-manifolds and 2d 𝒩=(0, 2) N=(0, 2) theories, we …

A bstract We describe the first order moduli space of heterotic string theory compactifications
which preserve N= 1 supersymmetry in four dimensions, that is, the infinitesimal parameter …

We study the 6d $\mathcal {N}=(1, 0) $ superconformal field theory with smallest non-
Higgsable gauge symmetry $ SU (3) $. In particular, we propose new 2d gauge theory …

A bstract In this paper we study compactifications of heterotic string theory on manifolds
satisfying the\(\partial\overline {\partial}\)-lemma. We consider the Strominger system …

It was recently argued by Nguyen-Tanizaki-Unsal that two-dimensional pure Yang-Mills
theory is equivalent to (decomposes into) a disjoint union of (invertible) quantum field …

A bstract Motivated by the connection between 4-manifolds and 2d\(\mathcal {N}\)=(0, 2)
theories, we study the dynamics of a fairly large class of 2d\(\mathcal {N}\)=(0, 2) gauge …

A bstract We consider finite deformations of the Hull-Strominger system. Starting from the
heterotic superpotential, we identify complex coordinates on the off-shell parameter space …

A bstract We study heterotic supergravity at\(\mathcal {O}\left (\alpha^{\prime}\right)\), first
described in detail in 1989 by Bergshoeff and de Roo. In particular, we discuss the …

Compactifications of 6D superconformal field theories (SCFTs) on four-manifolds generate a
large class of novel 2d quantum field theories. We consider in detail the case of the rank one …

Heterotic string compactifications on integrable G 2 structure manifolds Y with instanton
bundles (V, A),(TY, ̃ θ)(V, A),(TY, θ~) yield supersymmetric three-dimensional vacua that are …
