Intersection of holonomy varieties of $C P^{1}$ -structures

Shinpei Baba

Let $Σ$ be a closed orientable surface of genus at least two, and let $X, Y$ be distinct marked Riemann surface structures on $Σ$ , possibly with opposite orientations. In this pape…

Bending Teichmüller spaces and character varieties

Shinpei Baba

We consider the mapping $b_{L} : T \to χ$ from the Fricke-Teichmüller space $T$ into the $PSL_{2} C$ -character variety $χ$ of the surface, obtai…

Realisation of bending measured laminations by Kleinian surface groups

Shinpei Baba, Ken'ichi Ohshika

For geometrically finite Kleinian surface groups, Bonahon and Otal proved the existence part, and partly the uniqueness part of the bending lamination conjecture. In this paper, we…

Bers' simultaneous uniformization and the intersection of Poincare holonomy varieties

Shinpei Baba

We consider the space of ordered pairs of distinct $C P^{1}$ -structures on Riemann surfaces (of any orientations) which have identical holonomy, so that the quasi-Fuchsian sp…

Neck-Pinching of $C P^{1}$ -structures in the $P S L (2, C)$ -character variety

Shinpei Baba

We characterize a certain neck-pinching degeneration of (marked) $C P^{1}$ - structures on a closed oriented surface S of genus at least two. Namely, we consider a path $C_{t}$ of $C P^{1}$ …

On Thurston's parametrization of $C P^{1}$ -structures

Shinpei Baba

Thurston related $C P^{1}$ -structures (complex projective structures) and equivariant pleated surfaces in the hyperbolic-three space $H^{3}$ , in order to give a…

Holonomy map fibers of $C P^{1}$ -structures in moduli space

Shinpei Baba, Subhojoy Gupta

Let $S$ be a closed oriented surface of genus $g \geq 2$ . Fix an arbitrary non-elementary representation $ρ : π_{1} (S) \to SL_{2} (C)$ and consider all marked (complex)…

2π-grafting and complex projective structures with generic holonomy

Shinpei Baba

Let S be an oriented closed surface of genus at least two. We show that, given a generic representation in the PSL(2,C)-character variety of S, (2π-)graftings produce all projectiv…

2 π-grafting and complex projective structures, I

Shinpei Baba

Let $S$ be a closed oriented surface of genus at least two. Gallo, Kapovich, and Marden asked if 2π-graftings produce all projective structures on $S$ with arbitrarily fixed holono…

Complex projective structures with Schottky holonomy

Shinpei Baba

A Schottky group in PSL(2, C) induces an open hyperbolic handlebody and its ideal boundary is a closed orientable surface S whose genus is equal to the rank of the Schottky group.…

A Schottky decomposition theorem for complex projective structures

Shinpei Baba

Let S be a closed orientable surface of genus at least two, and let C be an arbitrary (complex) projective structure on S. We show that there is a decomposition of S into pairs of…
