WebHilbert is a browser-based editor for direct proofs (also called Hilbert-style proofs). The system focusses on implicational logic, i.e. logic in which the language is restricted to negation, implication, and universal quantification.

WebA Hilbert-style deduction system uses the axiomatic approach to proof theory. In this kind of calculus, a formal proof consists of a finite sequence of formulas $\alpha_1, ..., \alpha_n$, where each $\alpha_n$ is either an axiom or is obtained from the previous formulas via an application of modus ponens. WebHilbert.doc:1998/03/27:page 7 of 16 It is sometimes convenient to represent the proof with a directed acyclic graph (DAG), rather than with a linear list. This makes transparent the …
