The CSU math graduate students have started writing a really fun monthly math magazine for the department, featuring stories, mathematical tidbits, and puzzles collected from the department and slid under all the professors’ doors each month.

I haven’t posted in a while; it’s time to dust off this blog and get things started again with a guest post!

In this arXiv paper, Hikita recently posted a proof of the famous Stanley-Stembridge conjecture!

I have written about the flag variety, the Springer resolution, and the relation between the type A Springer correspondence and Hall-Littlewood polynomials in a previous sequence of posts.

After a bit of a hiatus due to difficulties with Wordpress, Mathematical Gemstones is back!

Time for a just-for-fun combinatorial problem!
