Collins–Yau conjecture on dHYM solutions and Bridgeland stability

Let XX be the compact Kähler manifold under consideration, and let LL be a holomorphic line bundle on XX. A metric solving the deformed Hermitian–Yang–Mills equation is a metric on LL satisfying that equation, and Db(Coh(X))D^b(\operatorname{Coh}(X)) denotes the bounded derived category of coherent sheaves on XX. Collins–Yau conjecture. LL admits a metric solving the deformed Hermitian–Yang–Mills equation if and only if LL is a Bridgeland stable object in

Db(Coh(X)).D^b(\operatorname{Coh}(X)).

This conjecture proposes an equivalence between the differential-geometric existence problem for the deformed Hermitian–Yang–Mills equation and Bridgeland stability for line bundles. Its resolution is not specified in the supplied source context.
