Reflection principles, GCH and the uniformization properties

Jing Zhang

Research output: Contribution to journalArticlepeer-review


Reflection principles (or dually speaking, compactness principles) often give rise to combinatorial guessing principles. Uniformization properties, on the other hand, are examples of anti-guessing principles. We discuss the tension and the compatibility between reflection principles and uniformization properties at the level of the second uncountable cardinal.
