要 旨 | Using a presentation for the partition algebras given by Halverson and Ram, we provide a recursive definition for a large family of commuting (Jucys–Murphy) elements in the partition algebras, and an integral Murphy-type basis for the partition algebras, with respect to which the commuting family acts triangularly. Schur–Weyl will show that this recursively defined commuting family of Jucys-Murphy elements coincides exactly with the family of commuting elements given diagrammatically by Halverson and Ram. Our presentation will conclude with a discussion of further applications of the Jucys–Murphy elements to the study of the representations of the partition algebras. | |||
