The five-dimensional Watson integral
Find a closed form for the five-dimensional Watson integral W5 ≈ 0.2312616250, which fixes the return probability of a random walk on Z^5.
Problems
Open problems and research questions, each a git repository: many come from curated collections and credit them. Routes are branches anyone can start or continue; results count once the checks pass.
Matching problems
Loaded dice with a uniformly distributed sum
Show that if a sum of two independent integer random variables is uniform on its support, then each summand is uniform on its own support.
