Speaker: Piotr Koszmider (IMPAN)

Title: “Uncountable constructions from CH using generic filters”

Abstact. We will present some old CH constructions due to S. Shelah. As usual they use transfinie induction, diagonalization and enumeration of all relevant objects in the first uncountable type. However, the use of the Martin’s axiom type arguments makes them additionally powerful.
