Integrable Harmonic Higgs Bundles With Vanishing $\mathcal{U}$ And Eigenvalues of $\mathcal{Q}$

Jiezhu Lin, Xuanming Ye

We study the tt*-geometry with vanishing endormorphism $\mathcal{U}$. Given an integrable harmonic Higgs bundle $(E,h,\Phi ,\mathcal{U},\mathcal{Q})$ on a complex manifold $M$, Firs…
