Doubly robust pointwise confidence intervals for a monotonic continuous treatment effect curve
We study nonparametric inference for the causal dose-response (or treatment effect) curve when the treatment variable is continuous rather than binary or discrete. We do this by developing doubly robust confidence intervals for the continuous treatment effect curve (at a fixed point) under the assumption that it is monotonic, based on inverting a likelihood ratio-type test. Monotonicity of the treatment effect curve is often a very natural assumption, and this assumption removes the need to cho…

Distinguishing Curve Types and Designer Metrics
Let $γ$ be a filling curve on a topological surface $Σ$ of genus $g \geq 2$. The inf invariant of $γ$, denoted $m_γ$, is the infimum of the length function on the space of marked hyperbolic structures on $Σ$. This infimum is realized at a unique hyperbolic structure, $X_γ$, which we call the optimal metric associated to $γ$. In this paper, we investigate properties of the inf invariant and its associated optimal metric. Starting from a filling curve and a separating curve, we construct a…

Hyperbolic spaces not quasi-isometric to curve complexes
We identify a condition that prevents a hyperbolic space from being quasi-isometric to the curve complex of any non-sporadic surface. Our result applies to several hyperbolic complexes, including arc complexes, disk complexes, non-separating curve complexes, (hyperbolic) pants complexes, and to free splitting complexes of free groups.
