Tube classes over elementary vanishing cycles

Erjuan Fu

Let $X$ be a closed Riemann surface. When $X$ is embedded into a projective space, the first rational cohomology group can be concretely obtained from the monodromy in the family o…

A new approach towards Lefschetz $(1, 1)$ -Theorem

Erjuan Fu

Let $S$ be a complex projective surface. Lefschetz originally proved Lefschetz $(1, 1)$ --Theorem by studying a Lefschetz pencil of hyperplane sections of $S$ and the Abel--Jacobi m…

A necessary and sufficient condition for the Darboux-Treibich-Verdier potential with its spectrum contained in $R$

Zhijie Chen, Erjuan Fu, Chang-Shou Lin

In this paper, we study the spectrum of the complex Hill operator $L = \frac{d ^{2}}{d x ^{2}} + q (x; τ)$ in $L^{2} (R, C)$ with the Darboux-Treibich-Verdier potential \[q(x;τ):=…
