By work of Cassels, Poonen, Schaefer and others, the 2-Selmer group of a hyperelliptic curve C admits an explicit description in terms of the arithmetic of the number fields defined by the polynomial defining C. In this talk, I will describe an analogous explicit arithmetic description of more complicated Selmer groups associated not to abelian varieties but to higher Chow groups. I will also give some applications to determining the set of rational points on hyperelliptic curves of large Mordell—Weil rank.
