Mirror of Orbifold Singularities in the Hitchin Fibration: the case $(SL_{n}, PGL_{n})$

Yongbin Ruan, Cheng Shu

We study the geometry of singular $SL_{n}$ -Hitchin fibres over the elliptic locus. We show that orbifold singularities appear in the $PGL_{n}$ -moduli space $M^{ell}(\text…

E-Polynomials of Generic $GL_{n} ⋊ < σ >$ -Character Varieties: Unbranched Case

Cheng Shu

For any unbranched double covering of compact Riemann surfaces, we study the associated character varieties that are unitary in the global sense, which we call $\text{GL}_n\rtimes\…

E-Polynomials of Generic $GL_{n} ⋊ < σ >$ -Character Varieties: Branched Case

Cheng Shu

For any branched double covering of compact Riemann surfaces, we consider the associated character varieties that are unitary in the global sense, which we call $\text{GL}_n\rtimes…
