Cheerful news in difficult times: Richard Stanley wins the Steele Prize for lifetime achievement!
Richard Stanley, a most famous and influential mathematician in my area of combinatorics, the master of finding deep connections between combinatorics and other areas of pure mathematics, and my postdoctoral advisor, has just won the Steele prize for lifetime achievement, … Continue reading
Combinatorial Theory is Born
A few hours ago the first issue of Combinatorial Theory was published. I am happy and proud to take part in this new endeavor. The editorial speaks for itself. This is the first issue of our new journal, Combinatorial Theory. … Continue reading
Good Codes papers are on the arXiv
Here are some links to the breakthrough papers about error correcting codes that I mentioned in this post. The results about locally testable codes with constant rate distance and locality was achieved independently in papers 1 and 2. 1) Locally … Continue reading
To cheer you up in difficult times 33: Deep learning leads to progress in knot theory and on the conjecture that KazhdanLusztig polynomials are combinatorial.
One of the exciting directions regarding applications of computers in mathematics is to use them to experimentally form new conjectures. Google’s DeepMind launched an endeavor for using machine learning (and deep learning in particular) for finding conjectures based on data. Two … Continue reading
