Grassmannian code[13] 

Description

Evaluation code of polynomials evaluated on points lying on a Grassmannian \({\mathbb{G}}(\ell,m)\).

Parent

  • Flag-variety code — Grassmannian codes are flag-variety evaluation codes with the flag variety being a Grassmannian.

Cousins

  • Griesmer code — The binary Grassmannian \([35,6,16]\) code, whose points lie on the Grassmannian \({\mathbb{G}(2,4)}\), attains the Griesmer bound [4].
  • Schubert code — Schubert varieties are subvarieties of Grassmannians, and Schubert codes were initially constructed as a generalization of Grassmannian codes.
