Charges, complex structures, and perturbations of instantons
Lars Andersson, Bernardo Araneda
Hermitian non-Kähler Einstein 4-manifolds have a quasi-locally conserved charge associated to spin-lowering via Killing spinors, and corresponding to a parameter of the moduli spa…

Mode Stability of Hermitian Instantons
Lars Andersson, Bernardo Araneda, Mattias Dahl
In this note, we prove the Riemannian analog of black hole mode stability for Hermitian, non-self-dual gravitational instantons which are either asymptotically locally flat (ALF) a…
