Cyclotomic factors and irreducibility of the denominators of -deformed rational numbers

Kengo Miyamoto

For the -deformed modular group specialized at a primitive -th root of unity is the triangle group of type . Using this we determine the fractions for…

Conway Symbols of Frieze Patterns of Dynkin Types

Kengo Miyamoto, Ryuhei Suzuki

In this paper, we classify the Conway symbols of the Euclidean symmetry groups of frieze patterns of Dynkin types , , , , and . First, we show that t…

Frobenius--Perron dimension and tensor products of algebras

Kengo Miyamoto

In this paper, we study how the Frobenius--Perron dimension of finite-dimensional algebras behaves under tensor products and related constructions. We prove that Frobenius--Perron…

Defect Spaces and Gram Operators for Tensor-Valued Incidence Maps

Kengo Miyamoto

We study vector-valued incidence maps obtained from ordinary graph incidence maps by linear observation of the free vertex space. Let be a field, a…

Arithmetic on -deformed rational numbers

Takeyoshi Kogiso, Kengo Miyamoto, Xin Ren +2

Recently, Morier-Genoud and Ovsienko introduced a -deformation of rational numbers. More precisely, for an irreducible fraction , they constructed coprime polynomia…

Uniform Cyclic Group Factorizations of Finite Groups

Kazuki Kanai, Kengo Miyamoto, Koji Nuida +1

In this paper, we introduce a kind of decomposition of a finite group called a uniform group factorization, as a generalization of exact factorizations of a finite group. A group $…

Automorphism Shuffles for Graphs and Hypergraphs and Its Applications

Kazumasa Shinagawa, Kengo Miyamoto

In card-based cryptography, a deck of physical cards is used to achieve secure computation. A shuffle, which randomly permutes a card-sequence along with some probability distribut…

Graph Automorphism Shuffles from Pile-Scramble Shuffles

Kengo Miyamoto, Kazumasa Shinagawa

A pile-scramble shuffle is one of the most effective shuffles in card-based cryptography. Indeed, many card-based protocols are constructed from pile-scramble shuffles. This articl…

Report on the finiteness of silting objects

Takuma Aihara, Takahiro Honma, Kengo Miyamoto +1

We discuss the finiteness of (two-term) silting objects. First, we investigate new triangulated categories without silting object. Second, one studies two classes of -tilting-fi…
