Monodromy of Primitive Vanishing Cycles for Hypersurfaces in
Yilong Zhang
Let X be a complex submanifold of projective space. Schnell showed that the middle-dimensional primitive cohomology of X is generated by tube classes, which arise from the monodrom…

Degeneration of Dual Varieties of Hypersurfaces
Yilong Zhang
Consider a one-parameter family of smooth projective varieties X_t which degenerate into a simple normal crossing divisor at t=0. What is the dual variety in the limit? We answer t…
