時間：16日（月）と18日（水）1:20-2:50
アブストラクト：
There are many connections between classical topological problems
concerning Lindelöf spaces and selection principles, such as
(generalizations of) Rothberger, Menger, and Hurewicz properties.
In the first talk, we will discuss these connections.
In the second talk, we will pursue further some of the topics introduced in
the first talk, but it is not necessary to have gone to the first talk in order
to understand the second.

題目：PFA(S)[S]: a useful model (talk 3)
時間：19日（木）3:10-4:40
アブストラクト：
We introduce a model in which important consequences of PFA hold
but also some combinatorics that follow from V=L. This talk is
quite technical and assumes familiarity with proper forcing with
elementary submodels as side conditions.
