摘要：In this talk, I'll introduce the isotopy problems for Lagrangian spheres in algebraic surfaces. Smooth isotopy problems on rational surfaces are resolved by work of Matthew Borman, Tian-Jun Li and Weiwei Wu, while for non-rational surfaces little is known. I'll present my recent work with Yilong Zhang on generalizing the result of Borman, Li and Wu to certain non-rational algebraic surfaces via Hodge theoretic techniques.
