MathAdv: What Theorem Provers Know, Reason, Formalize, and Generalize

Wenqian Ye, Ziwei Guan, Eric Xie et al.

Automated theorem proving offers a natural foundation for recursive self-improvement in scientific discovery. However, existing neural provers do not fully preserve this recursive structure, where the learning process should be self-improving over time. Exi...

A deterministic sin^2-type algorithm for complex cubic irrationalities with exact periodicity certificates

Ludovic Tagnon

Hermite asked in 1848 for a representation of real numbers whose eventual periodicity characterizes cubic irrationals. The totally real case was solved by Karpenkov's $\sin^2$-algorithm; the complex case, signature (1,1), is his Problem 4. We study a determ...

Fine Difference Structure and Prime-Power Depth of Bent Partitions

Zhaorui Wu

A $p$-ary bent partition of $\mathbb{F}_p^n$ is a partition into $K$ nonempty cells such that every balanced assignment of its cells to $\mathbb{F}_p$ produces a bent function. It was asked whether every possible depth $K$ is a power of $p$; for general $p$...

Explicit gauge-invariant variables in multifield inflation beyond linear order and Hamiltonian dynamics
