| [[Yang–Baxter operator]] <small>(A mathematical operator used in theoretical physics and topology)</small>
| Yang–Baxter operators are [[invertible]] [[linear operator|linear]] [[endomorphisms]] with applications in [[theoretical physics]] and [[topology]]. They are named after [[theoretical physicists]] [[Yang Chen-Ning]] and [[Rodney Baxter]]. These [[mathematical operator|operators]] are particularly notable for providing solutions to the quantum [[Yang–Baxter equation]], which originated in [[statistical mechanics]], and for their use in constructing [[Knot invariant|invariants]] of [[knot theory|knots]], links, and three-dimensional [[manifolds]].
