sequent calculus

Sequent Calculus is a formal system used in mathematical logic to represent and manipulate logical arguments. It consists of sequents, which are expressions showing that a set of premises leads to a conclusion. This system allows for the systematic application of rules that govern how conclusions can be drawn from premises. By using these rules, one can construct proofs or verify the validity of arguments. Sequent Calculus is foundational in understanding formal proofs and has applications in computer science, especially in areas like automated theorem proving and programming language semantics.
