Algebraization

Definition

Algebraization refers to the process of transforming logical statements or proofs into algebraic forms, making them easier to analyze and manipulate. This technique connects proof complexity and computational complexity by allowing for the use of algebraic structures to study the efficiency and expressiveness of proof systems. It bridges the gap between discrete mathematics and algebra, helping to clarify relationships between different logical frameworks.
