An Erdős–Rado theorem for perfect trees [PDF]
- JORGE CRUZ CHAPITAL, University of Toronto

The Erdős–Rado theorem states that any equivalence relation on $[\omega]^k$ can be reduced to a \emph{canonical} equivalence relation on $[M]^k$ for some infinite $M$. In this joint work in progress with Unger, we establish an analogous result for equivalence relations on certain finite trees inside perfect trees.
