✍ Steffen König 📂 Article 📅 1999 🏛 Elsevier Science 🌐 English ⚖ 274 KB

Strong exact Borel subalgebras and strong 2-subalgebras are shown to exist for quasi-hereditary algebras which possess exact Borel subalgebras and 2-subalgebras. This implies that the algebras associated with blocks of category O have strong exact Borel subalgebras and strong 2-subalgebras. The stru
