Generating Sets

Definition

Generating sets are collections of elements in a mathematical structure that can be combined through specific operations to produce all elements of that structure. In the context of tropical algebra, generating sets play a crucial role in understanding the relationships between tropical polynomials and their corresponding tropical varieties, especially as they relate to the Tropical Nullstellensatz.
