Solutions and singularities of the Ricci-harmonic flow and Ricci-like flows of $G_{2}$ -structures

Shubham Dwivedi, Ragini Singhal

We find explicit solutions and singularities of the Ricci-harmonic flow of $G_{2}$ -structures, the Ricci-like flows of $G_{2}$ -structures studied by Gianniotis-Zachar…

Examples of real stable bundles on K3 surfaces

Dino Festi, Daniel Platt, Ragini Singhal +1

Motivated by gauge theory on manifolds with exceptional holonomy, we construct examples of stable bundles on K3 surfaces that are invariant under two involutions: one is holomorphi…

Revisiting 3-Sasakian and $G_{2}$ -structures

Simon Salamon, Ragini Singhal

The algebra of exterior differential forms on a regular 3-Sasakian 7-manifold is investigated, with special reference to nearly-parallel $G_{2}$ 3-forms. This is applied to the study…
