Some Results in Finite Combinatorics
I survey some (recent) results in finite combinatorics inspired by considerations from mathematical logic. These include a formula for Goodstein’s function, the rate of growth of the regressive Ramsey numbers, and the size of intersecting families of finite sets that are minimal under definability.
