C-gluing construction and slices of quasi-Fuchsian space

Abstract: Given a pants decomposition $\mathcal{PC} = {\gamma_1, \ldots, \gamma_{\xi}}$ on a hyperbolizable surface $\Sigma$ and a vector $\underline{c} = (c_1, \ldots, c_{\xi}) \in \mathbb{R}+^\xi$, we describe a plumbing construction which endows $\Sigma$ with a complex projective structure for which the associated holonomy representation $\rho$ is quasi-Fuchsian and for which $\ell\rho(\gamma_i) = c_i$. When $\underline{c} \to \underline{0} = (0, \ldots, 0)$ this construction limits to Kra's plumbing construction. In addition, when $\Sigma = \Sigma_{1,1}$, the holonomy representations of these structures belong to the `linear slice' of quasi-Fuchsian space $\mathrm{QF}(\Sigma)$ defined by Komori and Parkonnen. We discuss some conjectures for these slices suggested by the pictures we created in joint work with Yamashita.
