摘要：In joint work with Xiangfei Li, we study the associated trace polynomials for closed curves on the enlarged modular torus. For the coefficient sequences of the polynomials, we prove positivity for all curves, and log-concavity for all simple closed curves. We observe the same phenomina for enlarging all hyperbolic tori.
