Ricci-flat metrics from gauged linear -models without RG flow
Dmitri Bykov, Ondrej Hulik, Ulf Lindström +2
We investigate a class of Ricci-flat Kähler metrics on generalized conifolds constructed via gauged linear sigma models (GLSMs) with indefinite signature. By introducing shadow coo…
Gauss law constraint in A-theory branes
Machiko Hatsuda, Ondrej Hulık, Ondrej Hulık +3
A-theory realizes U-duality symmetry by extending the string worldsheet to a higher dimensional brane worldvolume, in which the worldvolume and the spacetime belong to different re…
BCOV on the Large Hilbert Space
Eugenia Boffo, OndÅej HulÃk, Ivo Sachs
We formulate the BCOV theory of deformations of complex structures as a pull-back to the super moduli space of the worldline of a spinning particle. In this approach the appearance…
Y-algebroids and -generalised geometry
Ondrej Hulik, Emanuel Malek, Fridrich Valach +1
We define the notion of Y-algebroids, generalising the Lie, Courant, and exceptional algebroids that have been used to capture the local symmetry structure of type II string theory…
Exceptional algebroids and type IIA superstrings
Ondrej Hulik, Fridrich Valach
We study exceptional algebroids in the context of warped compactifications of type IIA string theory down to dimensions, with . In contrast to the M-theory and type IIB…
