= Theta divisor
{wiki=Theta_divisor}
In mathematics, particularly in the theory of abelian varieties and algebraic geometry, a *Theta divisor* is a specific kind of divisor associated with a principally polarized abelian variety (PPAV). More formally, if \\( A \\) is an abelian variety and \\( \\Theta \\) is a quasi-projective variety corresponding to a certain polarization, then the theta divisor \\( \\theta \\) is defined as the zero locus of a section of a line bundle on \\( A \\).
