Title:
RC-positivity and scalar-flat metrics on ruled surfaces
Time & Venue:
2018.9.13 14:00-15:00 N913
Abstract:
Let X be a ruled surface over a curve of genus g. We show that X has a scalar-flat Hermitian metric if and only if g is greater than one and m(X) is greater than 2-2g where m(X) is an intrinsic number depends on the complex structure of X. This a joint work with Prof. Xiaokui Yang.
