The Extender Algebra and its Variants

School
MATHEMATICS

This lecture course discusses criteria for when V is a generic extension
of a given inner model. Bukowsk and Balcar identified beautiful and handy criteria
in the 1970'ies which got applied recently in set theoretical geology. Later, Woodin
isolated his extender algebra which makes use of a large cardinal, a Woodin
cardinal. It turns out that Bukowsk's and Woodin's approaches may be presented
in a uniform fashion. We will presuppose only basic knowledge of forcing,
present Bukowsk's and Woodin's results in a general framework, and discuss
applications in set theoretic geology and descriptive ...

On Generalizations of the Gromov-Hausdorff Metric

School
MATHEMATICS

Gromov has defined a metric on the set of all compact metric spaces. This metric is defined for group-theoretic purposes but has found important applications in probability theory as well. Also, there exist several generalizations of this metric. For instance, the Gromov-Hausdorff-Prokhorov metric defines the distance of two measured metric spaces. Other examples consider metric spaces equipped with a distinguished point, a closed subset, a curve, a tuple of such structures, etc. In this talk, a general approach is presented for generalizing the Gromov-Hausdorff metric to consider metric spaces equipped with some additional structure. This a ...
