On the enumeration of Fano Bott manifolds
Yunhyung Cho, Eunjeong Lee, Mikiya Masuda +1
Fano Bott manifolds bijectively correspond to signed rooted forests with some equivalence relation. Using this bijective correspondence, we enumerate the isomorphism classes of Fan…
Toric Richardson varieties of Catalan type and Wedderburn-Etherington numbers
Eunjeong Lee, Mikiya Masuda, Seonjeong Park
We associate a complete non-singular fan with a polygon triangulation. Such a fan appears from a certain toric Richardson variety, called of Catalan type introduced in this paper.…
Small toric resolutions of toric varieties of string polytopes with small indices
Yunhyung Cho, Yoosik Kim, Eunjeong Lee +1
Let be a semisimple algebraic group over . For a reduced word of the longest element in the Weyl group of and a dominant integral weight , one can co…
Algebraic and geometric properties of flag Bott-Samelson varieties and applications to representations
Naoki Fujita, Eunjeong Lee, Dong Youp Suh
We introduce the notion of flag Bott-Samelson variety as a generalization of Bott-Samelson variety and flag variety. Using a birational morphism from an appropriate Bott-Samelson v…
