The stability of non-Kähler Calabi-Yau metrics

Non Kähler Calabi Yau theory is a newly developed subject and it arises naturally in mathematical physics and generalized geometry. The relevant geometrics are pluriclosed metrics which are critical points of the generalized Einstein Hilbert action. In this work, we study the critical points of the generalized Einstein Hilbert action and discuss the stability of critical points which are defined as pluriclosed steady solitons. We proved that all Bismut Hermitian Einstein manifolds are linearly stable which generalizes the work from Tian, Zhu, Hall, Murphy and Koiso In addition, all Bismut flat pluriclosed steady solitons with positive Ricci curvature are linearly strictly stable.
