Abelian integrals

Definition

Abelian integrals are a class of integrals associated with algebraic functions and are defined through the use of differential forms on algebraic curves. These integrals play a significant role in the study of algebraic geometry and number theory, particularly in relation to the properties of complex functions and their connections to group theory. Abelian integrals can be linked to the notion of abelian varieties, which are higher-dimensional generalizations of elliptic curves, highlighting their importance in understanding the interplay between algebraic structures and geometric forms.
