我们证明,紧黎曼曲面上的Higgs-Demailly系统在其终端参数处存在光滑容许解,当且仅当该希格斯丛是H-丰富的。这通过Griffiths正的Hitchin-Simpson曲率给出了H-丰富性的独立解析刻画。证明扩展了Demailly-Pingali-Murakami的方法,利用先验估计和Leray-Schauder度理论;缺失的标量下界由希格斯相容商构造得到:爆破序列产生非零的非正次数希格斯商,与H-丰富性矛盾。
英文摘要
We prove that the Higgs--Demailly system on a compact Riemann surface admits, for suitable fixed parameters, a smooth admissible solution at its terminal parameter if and only if the Higgs bundle is H-ample. Here H-ampleness is understood in the modified sense of Biswas--Misra--Ray. In particular, the argument gives an analytic proof of the equivalence between this H-ampleness and Griffiths-positive Hitchin--Simpson curvature. The proof extends the Demailly--Pingali--Murakami approach using a priori estimates and Leray--Schauder degree theory. The missing scalar lower bound follows from a Higgs-compatible quotient construction: a blow-up sequence produces a nonzero Higgs quotient of nonpositive degree, contradicting H-ampleness.
