Think Fast: Estimating No-CoT Task-Completion Time Horizons of Frontier AI Models
Dewi Gould, Francis Rhys Ward, Anders Cairns Woodruff +18
Many efforts to ensure frontier AI models are safe rely on monitoring their chain-of-thought (CoT) reasoning. If models become able to perform sufficiently complex reasoning intern…
LINGOLY-TOO: Disentangling Reasoning from Knowledge with Templatised Orthographic Obfuscation
Jude Khouja, Lingyi Yang, Karolina Korgul +6
Frontier language models demonstrate increasing ability at solving reasoning problems, but their performance is often inflated by circumventing reasoning and instead relying on the…
Cobordism and Concordance of Surfaces in 4-Manifolds
Simeon Hellsten
We show that two properly embedded compact surfaces in an orientable 4-manifold are cobordant if and only if they are -homologous and either the 4-manifold has bounda…
The Metaplectic Representation is Faithful
Christopher Chang, Simeon Hellsten, Mario Marcos Losada +1
We develop methods to show that infinite-dimensional modules over the Iwasawa algebra of a uniform pro-p group are faithful and apply them to show that the metaplectic represe…
