An unreleased research version of Claude made unexpected progress in number theory while attempting to solve the Riemann hypothesis, specifically increasing the known lower bound for the proportion of zeros on the critical line from 41.6% up to 67.2%. This mathematical breakthrough was validated by Anthropic mathematicians and produced a formally verifiable proof through Lean.
- The discovery occurred over two sessions using approximately 31 million output tokens via Claude Code.
- A team of about 60 subagents coordinated the research, running thousands of Python scripts and shell commands.
- To ensure novelty, the model cross-referenced its findings against 54 papers from arXiv.
Mathematicians have made significant progress on the long-stalled problem of improving bounds for near-diagonal Ramsey numbers by upgrading Paul Erdős’s probabilistic method with high-dimensional geometry. While Erdős' original 1947 technique used randomness to prove the existence of certain mathematical objects, it struggled to provide better estimates for specific graph structures over eight decades. Researchers Wujie Shen, Jie Ma, and Shengjie Xie overcame this by placing nodes on a high-dimensional sphere and coloring edges based on distance, leveraging unique geometric properties to achieve more precise lower bounds.
* The probabilistic method proves existence through probability rather than direct construction.
* Ramsey numbers measure the threshold at which certain patterns must emerge in colored graphs.
* New research integrates geometry into random models to improve estimates for near-diagonal Ramsey numbers.
AI models have entered a new era of problem-solving, successfully tackling long-standing mathematical conjectures—such as Erdös’s Unit Distance Problem and complex electrical flow problems in CS theory—through advanced reasoning and formal proof verification. This capability extends into creative domains, where AI is producing literature that challenges traditional distinctions between human and machine authorship. As these models accelerate, the role of humans may fundamentally shift from being primary solvers to high-level curators who define meaningful questions and interpret the solutions generated by artificial intelligence.
Mathematicians Dror Bar-Natan and Roland van der Veen have developed a breakthrough knot invariant that is both computationally efficient and highly effective at distinguishing complex knots. Traditionally, mathematicians had to choose between weak invariants that are easy to calculate and strong invariants that are nearly impossible to compute for large knots. This new tool uses a colorful hexagonal visual pattern—resembling a QR code—to represent mathematical data, allowing researchers to analyze knots with hundreds of crossings.
Key points:
* Solves the trade-off between computational speed and descriptive strength in knot theory.
* Uses a traffic-flow analogy inspired by subatomic particle behavior to model knot strands.
* Provides much higher accuracy than the Alexander or Jones polynomials.
* Potential applications include calculating the genus of large knots and uncovering deeper topological features.
This paper introduces a new class of "unbounded" spigot algorithms for calculating the decimal digits of $pi$, improving upon the classic Rabinowitz–Wagon method. While previous spigot algorithms required users to commit to a specific number of digits in advance and faced potential errors due to carry-over effects from truncated series, this proposed approach eliminates those limitations by allowing for infinite digit generation given sufficient memory. Although not intended to compete with high-performance state-of-the-art arithmetic-geometric mean algorithms, the author’s method offers a mathematically robust, simple, and incrementally efficient way to produce digits one by one without prior commitment or risk of truncation errors.

This article announces a new discrete mathematics course available on the freeCodeCamp.org YouTube channel, taught by Karol Kurek. Discrete mathematics is crucial for fields like machine learning and algorithms, enabling tasks such as finding shortest paths, encryption, and data compression. The course provides an introduction to key areas including combinatorics, number theory, prime numbers, and concepts like the pigeonhole principle and Chinese remainder theorem.
It also includes practical applications and implementations in Python. The course aims to equip learners with a strong foundation for further exploration in this evolving field.

A new proposal suggests that complexity increases over time, not just in living organisms but in the nonliving world, potentially rewriting notions of time and evolution. Researchers propose a law where entities are selected for richness in information enabling function, challenging traditional views and sparking debate about its testability and implications for understanding the universe.
