Abstract

Let EE be a holomorphic vector bundle over a compact K\"{a}hler manifold (X,ω)(X,\omega) with negative sectional curvature secK<0sec\leq -K<0, ΔE\Delta_{E} be the Chern connection on EE. In this article we show that if C:=[Λ,iΘ(E)]cnKC:=|[\Lambda,i\Theta(E)]|\leq c_{n}K, then (X,E)(X,E) satisfy a family of Chern number inequalities. The main idea in our proof is study the L2L^{2} ˉE~\bar{\partial}_{\tilde{E}}-harmonic forms on lifting bundle E~\tilde{E} over the universal covering space X~\tilde{X}. We also observe that there is a closely relationship between the eigenvalue of the Laplace-Beltrami operator ΔˉE~\Delta_{\bar{\partial}_{\tilde{E}}} and the Euler characteristic of XX. Precisely, if there is a line bundle LL on XX such that χp(X,Lm)\chi^{p}(X,L^{\otimes m}) is not constant for some integers p[0,n]p\in[0,n], then the Euler characteristic of XX satisfies (1)nχ(X)(n+1)+cnK2nC(-1)^{n}\chi(X)\geq (n+1)+\lfloor\frac{c_{n}K}{2nC} \rfloor.
