Note on adjacency spectra for twice punctured hypercubes
Jang Soo Kim, Victor Reiner, Laura Schoenzeit
Eigenspaces of hypercube graph adjacency matrices are well understood. We extend this to subgraphs obtained by removing a vertex or antipodal pair of vertices, motivated by a quest…
Bott manifolds of Bott--Samelson type and assemblies of ordered partitions
Junho Jeong, Jang Soo Kim, Eunjeong Lee
A Bott manifold is a smooth projective toric variety having an iterated -bundle structure. A certain family of Bott manifolds is used to understand the structure of…
Bounded Littlewood identities with fixed number of odd rows or odd columns
JiSun Huh, Jang Soo Kim, Christian Krattenthaler +1
A Littlewood identity is an identity equating a sum of Schur functions with an infinite product. A bounded Littlewood identity is one where the sum is taken over the partitions wit…
Hall--Littlewood expansions of chromatic quasisymmetric functions using linked rook placements
Jang Soo Kim, Seung Jin Lee, Meesue Yoo
In this work, we obtain a Hall--Littlewood expansion of the chromatic quasisymmetric function arising from a natural unit interval order and describe the coefficients in terms of l…
Hilbert polynomials of configuration spaces over graphs of circumference at most 1
Byung Hee An, Jang Soo Kim
The -configuration space of a topological space is the space of sets of distinct points in . In this paper, we consider the case where is a graph o…
Enumeration of multiplex juggling card sequences using generalized q-derivatives
Yumin Cho, Jaehyun Kim, Jang Soo Kim +1
In 2019, Butler, Choi, Kim, and Seo introduced a new type of juggling card that represents multiplex juggling patterns in a natural bijective way. They conjectured a formula for th…
