Semi-stability for bi-Holomorphic pairs over compact bi-Hermitian Gauduchon manifolds

In this paper, we investigate canonical metrics on bi-holomorphic bundles with a nontrivial global holomorphic section, and we prove that the I±\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$I_{\pm }$$\end{document}-holomorphic pair (E,∂¯+,∂¯-,ϕ)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(E,\bar{\partial }_{+},\bar{\partial }_{-},\phi )$$\end{document} is (α,τ)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\alpha ,\tau ) $$\end{document}-semi-stable if and only if it admits an approximate (α,τ)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\alpha ,\tau )$$\end{document}-Hermitian–Einstein structure over the compact bi-Hermitian manifold.
