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

β¦ Synopsis
It is proved that strong exact Borel subalgebras of quasi-hereditary algebra are conjugate to each other and are in bijection with the collection of maximal semisimple subalgebras.

In this article we begin an investigation of the conjugacy classes of Borel subalgebras together with Verma modules induced from ''standard'' Borel subalgebras of a toroidal Lie algebra α in two variables. We define, for each highest weight , a category O O of representations of α that contain these
