Closures of \(\text{SL}(2)\)-orbits in projective spaces
Let \(G = \text{SL} (2,\mathbb{C})\), and \(B\) a Borel subgroup. The author describes the closure of \(G\)-orbits and \(B\)-orbits in \(P(V)\), \(V\) being a regular \(G\)-module, by means of simple combinatorial data. The author also gives a criterion for determining whether the number of orbits in an orbit-closure is finite or not.
