Structural Proof Theory

Structural Proof Theory is a branch of mathematical logic that focuses on the relationships between different proofs and the structures they follow. Instead of examining proofs as isolated arguments, it studies the underlying frameworks, or "structures," that connect them. This approach helps to understand the nature of deduction and reasoning by comparing how different systems produce valid conclusions. It highlights the rules and principles that govern proof construction, revealing deeper insights into logic and mathematical systems, thus enhancing our understanding of how arguments can be systematically built and related to one another.
