Hamiltonian cycles for the square of the augmentation graphs and Gray codes for restricted permutations and ascent sequences
Autor: Tomie, Masaya
In this paper, we construct a listing for the vertices of the augmentation graph of given size, and as a consequence, we obtain a Hamiltonian cycle for the square of the augmentation graph of given size. As applications, we have a Gray code for the $

A relation between the shape of a permutation and the shape of the base poset derived from the Lehmer codes
Autor: Tomie, Masaya
For a permutation $\omega \in S_{n}$ Denoncourt constructed a poset $M_{\omega}$ which is the set of join-irreducibles of the Lehmer codes of the permutations in $[e, \omega]$ in the inversion order on $S_{n}$. In this paper we show that $M_{\omega}$

NBB bases of some pattern avoiding lattices
Autor: Tomie, Masaya
In this paper we will determine the NBB bases with respect to standard ordering of coatoms (resp.atoms) of 123-132-213-avoiding (resp.321-avoiding) lattices. Using these expression we will calculate the M\"obius numbers of 123-132-213-avoiding lattic

M\'obius numbers of some modified generalized noncrossing partitions
Autor: Tomie, Masaya
In this paper we will give a M\"obius number of $NC^{k}(W) \setminus \bf{mins} \cup \{\hat{0} \}$ for a Coxeter group $W$ which contains an affirmative answer for the conjecture 3.7.9 in Armstrong's paper [ Generalized noncrossing partitions and comb

A generalization of Chebyshev polynomials and non rooted posets
Autor: Tomie, Masaya
In this paper we give a generalization of Chebyshev polynomials and using this we describe the M\"obius function of the generalized subword order from a poset {a1,...as,c |ai

CLASSIFICATION OF POINTED REFLECTION SPACES
Autor: Azam, Saeid, Tomie, Masaya, Yoshii, Yoji
Publikováno v: Osaka Journal of Mathematics. 58(3):563-589
We classify isomorphism and similarity classes of pointed reflection spaces of residue ≤ 2. This leads to the classification of reduced extended affine root systems whose involved pointed reflection spaces have residue ≤ 2.
