What r/math is talking about this week

This post is to announce that there will be a lecture course on General Topology (a.k.a. Point-Set Topology) conducted in Mandelcord (the blue math discord server). Everyone is invited to join:...

Hello, I'd like to showcase some new results in tilings. This summer, I was contacted by a student named Alessandro Longo who tried to enumerate k-Euclidean tilings for his thesis. He eventually...

We know that a natural transformation between functors is a collection of morphisms which satisfies a certain commutative diagram. I have my own ways to to understand this: 1. Naturality vaguely...

This recurring thread will be for discussion of AI in mathematics. This includes, but is not limited to, the following: informal announcements of AI-assisted discoveries, such as those not yet...

My friend’s 7yo is already a math-enjoyer—he loved the book “Math for Curious Kids” and keeps wanting to find out more. I’ve found a few things that have been hits (a graph theory zine for kids, a...

Reading through Proofs From The Book and came across the assertion that given a set of k primes with k large and ordering the numbers that only have factors from this set, the sequence grows as...

There is Pascal triangle where the 2 numbers above are used to get the number below, then there is Delannoy triangle where the 3 numbers above are used to get the number below Based on that I...

Lately I've been enjoying exploring the connections between algebra in the natural numbers and combinatorics. It's a really rich vein of mathematics to play with and even though it's not an area...

This is a very general open-ended survey/discovery question and I already can predict the downvotes and toxic comments (as we always have) but I think it's appropriate for this subreddit as I...
