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…

Enumeration of Gelfand-Cetlin type reduced words

Yunhyung Cho, Jang Soo Kim, Eunjeong Lee

The combinatorics of reduced words and commutation classes plays an important role in geometric representation theory. A string polytope is a lattice polytope associated to each re…

Unique toric structure on a Fano Bott manifold

Yunhyung Cho, Eunjeong Lee, Mikiya Masuda +1

We prove that if there exists a -preserving graded ring isomorphism between integral cohomology rings of two Fano Bott manifolds, then they are isomorphic as toric varieties.…

Classification of six dimensional monotone symplectic manifolds admitting semifree circle actions

Yunhyung Cho

Let be a six dimensional closed monotone symplectic manifold admitting an effective semifree Hamiltonian -action. We show that is -equivariant symplec…

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…

A critical point analysis of Landau--Ginzburg potentials with bulk in Gelfand--Cetlin systems

Yunhyung Cho, Yoosik Kim, Yong-Geun Oh

Using the bulk-deformation of Floer cohomology by Schubert cycles and non-Archimedean analysis of Fukaya--Oh--Ohta--Ono's bulk-deformed potential function, we prove that every comp…
