Abstract
We prove that if is an infinite Boolean algebra in the ground model and is a notion of forcing adding any of the following reals: a Cohen real, an unsplit real, or a random real, then, in any -generic extension , has neither the Nikodym property nor the Grothendieck property. A similar result is also proved for a dominating real and the Nikodym property.
