Palestrante: Omar Selim, IME-USP

Título: More on exhaustive pathological submeasures

Resumo: Continuing from last week, I will give another proof that the ground model reals become small in extensions of exhaustive pathological submeasures. I will then introduce Talagrand's counter example to Maharam's problem and while doing so describe some of its absoluteness properties. From this one very quickly obtains the result that the collection of random reals in any such extension is measured as zero by Talagrand's submeasure.
