Speaker: Ding Longyun, Nankai University Tianjin

Title: Actions by Sequence Spaces

URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html

Abstract:
We investigate the Borel reducibility between equivalence relations of
the form as Reals^omega/G where G is a Borel subgroup of
Reals^omega. We are mainly interested on special cases
in which G is a Borel linear subspace. This kind of research
begin from Dougherty and Hjorth, while G is one of the classical
sequence spaces: lp (p geq 1) or c_0.

In this talk, we will recall some old results and introduce some new
results on this topic.
