摘要：The Z/2 harmonic 1-forms were introduced by Clifford Taubes to generalize the Uhlenbeck compactness theorem. These 1-forms turn out to be the 3-dimensional analog of quadratic differentials and can be used to compactify a character variety.

On the other hand, Z/2 eigensections generalize Laplacian eigenfunctions on S^2. Specifically, Z/2 critical eigensections serve as flat models for Z/2 harmonic 1-forms.In this talk, after an introduction to Z/2 harmonic 1-from, we will discuss existence of infinitely many Z/2 critical eigensections. This is joint work with S. He.
