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…
Maximum gap in cyclotomic polynomials
Ala'a Al-Kateeb, Mary Ambrosino, Hoon Hong +1
Cyclotomic polynomials play fundamental roles in number theory, combinatorics, algebra and their applications. Hence their properties have been extensively investigated. In this pa…
Torus orbit closures in flag varieties and retractions on Weyl groups
Eunjeong Lee, Mikiya Masuda, Seonjeong Park
A finite Coxeter group has a natural metric and if is a subset of , then for each , there is such that …
Toric Bruhat interval polytopes
Eunjeong Lee, Mikiya Masuda, Seonjeong Park
For two elements and of the symmetric group with in Bruhat order, the Bruhat interval polytope is the convex hull of the points $(z(1),…
Flag Bott manifolds of general Lie type and their equivariant cohomology rings
Shizuo Kaji, Shintarô Kuroki, Eunjeong Lee +1
In this article we introduce flag Bott manifolds of general Lie type as the total spaces of iterated flag bundles. They generalize the notion of flag Bott manifolds and generalized…
On the combinatorics of string polytopes
Yunhyung Cho, Yoosik Kim, Eunjeong Lee +1
For a reduced word of the longest element in the Weyl group of , one can associate the string cone which parametrizes the dual…
