Determining the primes of bad reduction of CM curves of genus 3

Sorina Ionica, Pinar Kiliçer, Kristin Lauter +3

In this paper we introduce a new problem called the Isogenous Embedding Problem (IEP). The existence of solutions to this problem is related to the primes of bad reduction of CM cu…

Limit theory of sparse random geometric graphs in high dimensions

Gilles Bonnet, Christian Hirsch, Daniel Rosen +1

We study topological and geometric functionals of -random geometric graphs on the high-dimensional torus in a sparse regime, where the expected number of neighbors decays…

Who Ate My Memory? Towards Attribution in Memory Management

Gunnar Kudrjavets, Ayushi Rastogi, Jeff Thomas +1

To understand applications' memory usage details, engineers use instrumented builds and profiling tools. Both approaches are impractical for use in production environments or deplo…

Chaotic light scattering around extremal black holes

Martijn Kluitenberg, Diederik Roest, Marcello Seri

We show that the scattering of light in the field of static extremal black holes is chaotic in the planar case. The relativistic dynamics of such extremal objects reduce…

V-LoTSS: The Circularly-Polarised LOFAR Two-metre Sky Survey

J. R. Callingham, T. W. Shimwell, H. K. Vedantham +44

We present the detection of 68 sources from the most sensitive radio survey in circular polarisation conducted to date. We use the second data release of the 144 MHz LOFAR Two-metr…

The Effects of Character-Level Data Augmentation on Style-Based Dating of Historical Manuscripts

Lisa Koopmans, Maruf A. Dhali, Lambert Schomaker

Identifying the production dates of historical manuscripts is one of the main goals for paleographers when studying ancient documents. Automatized methods can provide paleographers…
