Singular Loci of Ladder Determinantal Varieties and Schubert Varieties

✍ N. Gonciulea; V. Lakshmibai 📂 Article 📅 2000 🏛 Elsevier Science 🌐 English ⚖ 275 KB

We relate certain ladder determinantal varieties (associated to one-sided ladders) to certain Schubert varieties in SL n /Q, for a suitable n and a suitable parabolic subgroup Q, and we determine the singular loci of these varieties. We state a conjecture on the irreducible components of the singula
