Newton-Okounkov polytopes of type $A$ flag varieties of small ranks arising from cluster structures

Yunhyung Cho, Naoki Fujita, Akihiro Higashitani +1

A flag variety is a smooth projective homogeneous variety. In this paper, we study Newton-Okounkov polytopes of the flag variety $F l (C^{4})$ arising from its cluster structu…

$c_{1}$ -cohomological rigidity for smooth toric Fano varieties of Picard number two

Yunhyung Cho, Eunjeong Lee, Mikiya Masuda +1

The $c_{1}$ -cohomological rigidity conjecture states that two smooth toric Fano varieties are isomorphic as varieties if there is a $c_{1}$ -preserving isomorphism between their integra…

On combinatorics of string polytopes in types $B$ and $C$

Yunhyung Cho, Naoki Fujita, Eunjeong Lee

A string polytope is a rational convex polytope whose lattice points parametrize a highest weight crystal basis, which is obtained from a string cone by explicit affine inequalitie…
