RésumeWhat is common between the Specht construction for modules over permutation groups, normal sequences of quiver Hecke algebra modules à la Kashiwara-Kim, and the local Langlands classification for GL_n ? I would like to show how these themes fit well together under a framework of a representation-theoretic Robinson-Schensted-Knuth transform, devised recently in my work with Erez Lapid on representations of p-adic groups. On one hand, RSK-standard modules are curious models for all smooth irreducible GL_n-representations. Yet, going through Bernstein-Rouquier categorical equivalences this notion is quantized into its natural existence in the realm of type A quiver Hecke algebras. A convenient bridge is thus portrayed between the cyclotomic approach of classifying simple modules through a generalized Specht construction, and the PBW-basis approach from Lusztig's work on quantum groups.
