本文研究连通代数群上双陪集的交问题。在适当的假设下，我们证明了这种交叉是横截的，是光滑的不可约簇。我们还证明了交的闭包是闭包的交。
This paper deals with intersections of double cosets on a connected algebraic group. Under appropriate hypotheses, we show that such intersections are transversal and are smooth irreducible varieties. We also show that the closure of the intersection is the intersection of the closures.
