摘要⛹️‍♂️：Let H_q be the semisimple Hecke algebra of type D_n. To each simple module V over H_q(D_n), we explicitly construct a quasi-idempotent whose associated idempotent is a primitive idempotent associated to V. A matrix unit basis of H_q(D_n) is also obtained. We generalize some earlier work of Dipper, James, Murphy and Mathas to the type D_n setting.
