Additive configurations

Definition

Additive configurations refer to specific arrangements of numbers or elements within a set that satisfy particular additive properties or equations. These configurations are crucial for understanding the relationships and structures in additive combinatorics, especially when analyzing patterns and distributions in larger sets using tools like higher-order Fourier analysis.
