The Book That Made Me: A Girl, Daniel Pollack-Pelzner

Faculty Publications

In this installment of The Book That Made Me, a series from Public Books reflecting on the books that have changed our lives, Daniel Pollack-Pelzner reflects on the freedom he received—to become a whole other person, in a whole other place—from an unexpected source.

The Extinction And De-Extinction Of Species, Helena Siipi, Leonard Finkelman

Faculty Publications

In this paper, we discuss the following four alternative ways of understanding the outcomes of resurrection biology (also known as de-extinction). Implications of each of the ways are discussed with respect to concepts of species and extinction. (1) Replication: animals created by resurrection biology do not belong to the original species but are copies of it. The view is compatible with finality of extinction as well as with certain biological and ecological species concepts. (2) Re-creation: animals created are members of the original species but, despite their existence, the species remains extinct. The view is incompatible with all …

Infancia (In)Visible: La Subjetividad De La Niñez Como Transgresión A La Marginalidad En Las Películas Conducta Y Pelo Malo, Tania Carrasquillo Hernández

Faculty Publications

Tania Carrasquillo Hernández's research on race, gender, and sexuality has led her to develop a more specific interest in the study of childhood and sexuality in literature and cinema. This article, based on a presentation given at the Hispanic Literatures Across Cultures Conference (October 6–8, 2016 at Fresno Pacific University), analyzes the representation of boyhood and masculinity in contemporary Cuban and Venezuelan cinema via the films Conducta (2014, directed by Ernesto Daranas) and Pelo Malo (2013, directed by Mariana Rondón).

In the case of Chala (Armando Valdes Freire, Conducta), Carrasquillo Hernández explores how his masculinity is related to the …

Spectrally Similar Incommensurable 3-Manifolds, David Futer, Christian Millichap

Faculty Publications

Reid has asked whether hyperbolic manifolds with the same geodesic length spectrum must be commensurable. Building toward a negative answer to this question, we construct examples of hyperbolic 3–manifolds that share an arbitrarily large portion of the length spectrum but are not commensurable. More precisely, for every n ≫ 0, we construct a pair of incommensurable hyperbolic 3–manifolds N_n and N^µ_n whose volume is approximately n and whose length spectra agree up to length n.

Both N_n and N^µ_n are built by gluing two standard submanifolds along a complicated pseudo-Anosov map, ensuring that …

Mutations And Short Geodesics In Hyperbolic 3-Manifolds, Christian Millichap

Faculty Publications

In this paper, we explicitly construct large classes of incommensurable hyperbolic knot complements with the same volume and the same initial (complex) length spectrum. Furthermore, we show that these knot complements are the only knot complements in their respective commensurability classes by analyzing their cusp shapes.

The knot complements in each class differ by a topological cut-and-paste operation known as mutation. Ruberman has shown that mutations of hyperelliptic surfaces inside hyperbolic 3-manifolds preserve volume. Here, we provide geometric and topological conditions under which such mutations also preserve the initial (complex) length spectrum. This work requires us to analyze when least …
