On Pointed Hopf Algebras with Classical Weyl Groups
نویسنده
چکیده
Many cases of infinite dimensional Nichols algebras of irreducible YetterDrinfeld modules over classical Weyl groups are found. It is proved that except a few cases Nichols algebras of reducible Yetter-Drinfeld modules over classical Weyl groups are infinite dimensional. Some finite dimensional Nichols algebras of Yetter-Drinfeld modules over classical Weyl groups are given.
