A -Lemma and Bott--Chern-type Cohomology for Spin(7)-Manifolds
Shubham Dwivedi, Ragini Singhal
We study the properties of the -operator on -dimensional Spin(7)-manifolds with torsion-free Spin(7)-structures . These operators were first introduced by Harvey and La…

Solutions and singularities of the Ricci-harmonic flow and Ricci-like flows of -structures
Shubham Dwivedi, Ragini Singhal
We find explicit solutions and singularities of the Ricci-harmonic flow of -structures, the Ricci-like flows of -structures studied by Gianniotis-Zachar…

Ricci-harmonic flow of and Spin(7)-structures
Shubham Dwivedi
We introduce and study a new general flow of -structures which we call the Ricci-harmonic flow of -structures. The flow is the coupling of the Ricci flo…
