Colorful QR Codes Put Knot Theory on a Faster Track
TL;DR
A new knot invariant designed to be both strong and fast to compute outputs hexagonal QR-code images for each knot, enabling reliable distinction even for knots with hundreds of crossings and offering potential insights into genus and other topological features, with the work tying to the Kontsevich integral's two-loop approximation.
