本文主要地证明:由H-重模代数A,B构成的Smash积A#B的新对偶H(A#B)°恰好是由重模余代数HA°,HB°构成的Smash余积HA°× HB°;如果(H,σ)是辫化Hopf代数,则新对偶HH°是右,左H°-重模余代数;由量子Yang-Baxter H-模代数A,B构成的辫积A∝B的新对偶(A∝B)°恰好是由量子Yang-Baxter H-模余代数HA°,HB°构成的辫余积HA°×HB°,最后它给出由H-双模代数A构成的L-R Smash积AヰH的新对偶(AヰH)H°的正合序列。
In this paper, we prove that the new dual H(A#B)° of the Smash product A#B introduced by dimodule algebras A and B is a Smash coproduct HA°×HB° introduced by dimodule coalgebras HA° and HB°. If (H,σ) is a braided Hopf algebra, we show that HH° is a right, left H°-dimodule coalgebra, and then prove that the new dual H(A ∝ B)° of the braided product A ∝ B introduced by quantum Yang-Baxter module algebras A and B is a braided coproduct HA°×H B° introduced by quantum Yang-Baxter module coalgebras HA° and HB°. An exact sequence of the new dual (AヰH)H° of the L-R Smash product AヰH is given.
