QRes

a has a square root 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

QRes(m, a)

Exact expansion

exists qr_x_defined_qres. exists qr_u_defined_qres qr_v_defined_qres. qr_x_defined_qres * qr_x_defined_qres + m * qr_u_defined_qres = a + m * qr_v_defined_qres

This node is conservative notation, not a theorem, axiom, predicate constant, or kernel rule. Its expansion remains in the unchanged first-order language.

Reviewed QRes corresponds to blueprint QRes with checked argument positions [0, 1].

The global atlas describes planning vocabulary and does not itself certify a definition or theorem. The reviewed expansion and conservative dependency DAG on this page are the actual family-local reading definitions.
