Harmonic Higgs Bundles and Coassociative ALE Fibrations

Rodrigo Barbosa

Inspired by a string duality, we construct a deformation family for $G_{2}$ -orbifolds given as total spaces of coassociative fibrations by ADE singularities over a closed and oriente…

T-Branes and $G_{2}$ Backgrounds

Rodrigo Barbosa, Mirjam Cvetič, Jonathan J. Heckman +3

Compactification of M- / string theory on manifolds with $G_{2}$ structure yields a wide variety of 4D and 3D physical theories. We analyze the local geometry of such compactificatio…
