Definable Elements of Definable Borel Sets

Abstract:
We prove that it is true in Sacks, Cohen, and Solovay generic extensions that any ordinal definable Borel set of reals necessarily contains an ordinal definable element. This result has previously been known only for countable sets.
Keywords:
definable elements, Borel sets, Cohen forcing, Solovay forcing.
