Field-sub

Formalization and verification of a circuit for field subtraction.

Given two field elements x and y, their difference z is obtained via a constraint of the form

$(x\; -\; y)\; (1)\; =\; (z)$

Subtopics

Field-sub-spec

Specification of the circuit.

Field-sub-circuit

Construction of the circuit.

Field-sub-correctness

Correctness of the circuit.

Field-sub-lifting

Lifting of the circuit to a predicate.
