Example of C-rigid polytopes which are not B-rigid
Suyoung Choi, Kyoungsuk Park
A simple polytope is said to be \emph{B-rigid} if its combinatorial structure is characterized by its Tor-algebra, and is said to be \emph{C-rigid} if its combinatorial structu…
On alternating signed permutations with the maximal number of fixed points
Kyoungsuk Park
A conjecture by R. Stanley on a class of alternating permutations, which is proved by R. Chapman and L. Williams states that alternating permutations with the maximal number of fix…
Permutation statistics and weak {B}ruhat order in permutation tableaux of type
Soojin Cho, Kyoungsuk Park
Many important statistics of signed permutations are realized in the corresponding permutation tableaux or bare tableaux of type : Alignments, crossings and inversions of signed…
A combinatorial proof of a symmetry of -Eulerian numbers of type and type
Soojin Cho, Kyoungsuk Park
A symmetry of -Eulerian numbers of type is combinatorially proved by defining an involution preserving many important statistics on the set of permutation tableaux of ty…
A unification of the multiple twisted Euler and Genocchi numbers and polynomials associated with p adic q integral on Zp at q=-1
Serkan Araci, Mehmet Acikgoz, Kyoung Ho Park +1
The present paper deals with unification of the multiple twisted Euler and Genocchi numbers and polynomials associated with p-adic q-integral on Zp at q = 1. Some earlier results o…
Identities of symmetry for Bernoulli polynomials arising from quotients of Volkenborn integrals invariant under S_3
Dae San Kim, Kyoung Ho Park
In this paper, we derive eight basic identities of symmetry in three variables related to Bernoulli polynomials and power sums. These and most of their corollaries are new, since t…
