ScaledInverse

a and b are bounded units whose product is t modulo m.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.

Readable signature

ScaledInverse(m,t,a,b)

Exact expansion

(((~((a) = 0) /\ (exists dp_gap. dp_gap + S (a) = m))) /\ (((~((b) = 0) /\ (exists dp_gap. dp_gap + S (b) = m))) /\ (exists dp_u dp_v. (a) * (b) + m * dp_u = (t) + m * dp_v)))

This node is notation, not a theorem, axiom, predicate constant, or kernel rule. The elaboration layer must expand it before proof checking.
