Secant planes of a general curve via degenerations
Ethan Cotterill, Xiang He, Naizhen Zhang
We study linear series on a general curve of genus g, whose images are exceptional with respect to their secant planes. Each such exceptional secant plane is algebraically encoded…

Lifting divisors with imposed ramifications on a generic chain of loops
Xiang He
Proves that if a curve has totally split reduction and the corresponding skeleton (as a metric graph) is a chain of loops with generic edge lengths, then every divisor on the graph…

Smoothing of limit linear series on curves and metrized complexes of pseudocompact type
Xiang He
We investigate the connection between Osserman limit series (on curves of pseudocompact type) and Amini-Baker limit linear series (on metrized complexes with corresponding underlyi…
