Quadratically enriched binomial coefficients over a finite field
Chongyao Chen, Kirsten Wickelgren
We compute an analogue of Pascal's triangle enriched in bilinear forms over a finite field. This gives an arithmetically meaningful count of the ways to choose ring homomorphis…

On the generic degree of two-parameter period mappings
Chongyao Chen, Haohua Deng
We present a method for computing the generic degree of a period map defined on a quasi-projective surface. As an application, we explicitly compute the generic degree of three per…
