Newton polygons of cyclic covers of the projective line branched at three points

Wanlin Li, Elena Mantovan, Rachel Pries +1

We review the Shimura-Taniyama method for computing the Newton polygon of an abelian variety with complex multiplication. We apply this method to cyclic covers of the projective li…

Vanishing of Hyperelliptic L-functions at the Central Point

Wanlin Li

We obtain a lower bound on the number of quadratic Dirichlet L-functions over the rational function field which vanish at the central point . This is in contrast with the…

Doubly isogenous genus-2 curves with -action

Vishal Arul, Jeremy Booher, Steven R. Groen +5

We study the extent to which curves over finite fields are characterized by their zeta functions and the zeta functions of certain of their covers. Suppose C and C' are curves over…

The Ceresa class and tropical curves of hyperelliptic type

Daniel Corey, Wanlin Li

We define a new algebraic invariant of a graph called the Ceresa-Zharkov class and show that it is trivial if and only if is of hyperelliptic type, equivalently, does n…

A Miniaturised Camera-based Multi-Modal Tactile Sensor

Kaspar Althoefer, Yonggen Ling, Wanlin Li +3

In conjunction with huge recent progress in camera and computer vision technology, camera-based sensors have increasingly shown considerable promise in relation to tactile sensing.…

DexMani: Human-Derived Manipulability Guidance for Dexterous Rotation

Xiaoyang Chen, Shengcheng Luo, Haoran Guo +4

Dexterous object rotation is a sequential contact problem: each support, release, and re-contact decision must both produce the desired object motion, and prepare the hand configur…
