To every nonsingular algebraic curve $C$ (over the complex numbers) of genus $g$ one associates the Jacobian variety or simply Jacobian $J(C)$, either via differential 1-forms or equivalently via line bundles: the Jacobian is the moduli space of degree-$0$ line bundles over $C$, i.e. the connected component
of the neutral element of the Picard scheme of $C$. See also at intermediate Jacobian – Examples – Jacobian.
Jacobian varieties are the most important class of abelian varieties.
The Abel-Jacobi map $C\to J(C)$ is defined with help of periods.
Over the complex numbers, line bundles on a Jacobian variety over a given Riemann surface are naturally encoded by Riemann theta functions.
