A 50-year-old computer-assisted proof
3+ day, 13+ hour ago (254+ words) The idea of using computers to assist with proofs is not new. The first major computer-assisted proof was published in 1976, the proof of the four color theorem by Kenneth Appel and Wolfgang Haken. The authors reduced the proof of the…...
The part of Navier-Stokes no one is talking about
3+ day, 16+ hour ago (289+ words) Yesterday OpenAI announced a proof that settled a long-standing question about the Navier-Stokes equations from fluid dynamics. The announcement has created a lot of buzz, as one would expect. But there’s an aspect of OpenAI’s work that I haven’t seen…...
Exact equations discovered by computing the Gröbner basis
4+ day, 8+ hour ago (44+ words) Bioengineer.org Subject of Research: Exact equation discovery from noise-free data using Gröbner bases, evaluated on integer sequences from the Online Encyclopedia of Integer Sequences (OEIS) Article Title: Discovery of Exact Equations via Computing the Gröbner Basis...

Quantum Defects Reveal Links Between Symmetry And Topology
1+ week, 4+ day ago (257+ words) By combining these established concepts with new mathematical tools, the researchers have created a powerful method for exploring the intricacies of symmetry-enriched topological order and its implications for quantum materials. The findings, published in Quantum, represent a step towards a…...
Unit Circle & Radian Measure??? Free Game
2+ week, 1+ day ago (348+ words) Stellen Sie Ihre erste Frage Unit Circle and Radian Measure In early geometry, trigonometry is often limited to right triangles, which means we only deal with acute angles (between 0∘0^\circ0∘ and 90∘90^\circ90∘). By using the unit circle and radian measure, we can…...
Leetcode 41: First Missing Positive Integer
2+ week, 6+ day ago (239+ words) Base Cases: What if all the numbers are greater than n? Then we can simply return 1. For eg: [7,8,9,11,12]. Here all the numbers are greater than the length of the array, which is 5. In this case the first missing positive integer…...
Kirchhoff’s Matrix-Tree Theorem
2+ week, 6+ day ago (605+ words) This is just an incredible theorem that I recently came across; it’s so good that I had to write about it. It helps you find out the number of spanning trees of …...
I Was Solving the Same Problem Twice - I Just Didn’t Know It

Finding Equal Subset Sums in the Pigeonhole Regime by Prof Pranjal Dutta
3+ week, 2+ day ago (90+ words) Nanyang Technological University - NTU Singapore The Pigeonhole Equal Subset Sum problem (PESS), introduced by Papadimitriou (1994), asks: given n positive integers bounded by M with total sum less than 2^n − 1, find two distinct subsets with the same sum. A solution is…...
