报告摘要：

In my previous work with Peter Albers, we proved that the Rabinowitz Floer homology(RFH) for a circle subbundle of a negative line bundle vanishes if the radius of the circle is small. Later Sara Venkatesh showed that, in this setting, RFH is not always invariant under the change of radius by computing this for some examples. In this talk, I will explain how one can study the RFH of negative line bundles using the filtration given by the intersection number of Floer cylinders and the zero-section and then revisit the above computations. This is joint work with Peter Albers.
