摘要The 2021 Shaw Prize in Mathematical Sciences was awarded to Bismut and Cheeger, for their remarkable insights that have transformed, and continue to transform, modern geometry. The press release says that "Bismut and Cheeger have also worked together, and are particularly celebrated for their extension of a famous invariant, the so-called eta invariant, from manifolds to families of manifolds, which allowed them to compute explicitly the limit of the eta invariant along a collapsing sequence of spaces." Now this extension is called the Bismut-Cheeger eta form.

In this talk, we will introduce the celebrated Bismut-Cheeger eta form and explain our recent progresses on it.
