Sažetak
Consider a class of pairs (g, g_1), where g is a semisimple Lie algebra and g_1 is a subalgebra reductive in g, satisfying the following: For any Cartan subalgebra h_1 in g_1 there is a unique Cartan subalgebra h in g containing h_1. Given such a pair (g, g_1) and a Borel subalgebra b_1 in g_1 we study a (finite) set S_{; ; ; Bor}; ; ; ^g(b_1) of all Borel subalgebras b in g containing b_1. In particular we point at the subclass of pairs (g, g_1) when S_{; ; ; Bor}; ; ; ^g(b_1) is a singleton, for every Borel subalgebra b_1 in g_1. As a consequence, for such pairs we relate the corresponding flag varieties B(g) and B(g_1). As an interesting class of pairs (g, g_1), for which we can apply our results on pairs of Borel subalgebras, we study in detail the pairs considered by R. Brylinski and B. Kostant related to shared orbit pairs.
