摘要

We study two normal functions defined on the moduli space of smooth genus 4 algebraic curves including the Ceresa normal function. In particular, we study the vanishing criteria for the Griffiths infinitesimal invariants of both normal functions over a family of genus 4 curves with certain trigonal structures.
