Tangential morphisms via log arithmetic geometry
Yuichiro Hoshi, Makoto Matsumoto, Chikara Nakayama
We give a reformulation of tangential morphisms (which is a generalization of Deligne's tangential base point) via log geometry.
Some Patterns of Duplications in the outputs of Mersenne Twister Pseudorandom Number Generator MT19937
Alain Schumacher, Takuji Nishimura, Makoto Matsumoto
The Mersenne Twister MT19937 pseudorandom number generator, introduced by the last two authors in 1998, is still widely used. It passes all existing statistical tests, except for t…
A categorical proof of the nonexistence of (120, 35, 10)-difference sets
Hiroki Kajiura, Makoto Matsumoto
A difference set with parameters is a subset of cardinality in a finite group of order , such that the number of occurrences of as the rati…
A universal median quasi-Monte Carlo integration
Takashi Goda, Kosuke Suzuki, Makoto Matsumoto
We study quasi-Monte Carlo (QMC) integration over the multi-dimensional unit cube in several weighted function spaces with different smoothness classes. We consider approximating t…
Wreath products and projective system of non Schurian association schemes
Makoto Matsumoto, Kento Ogawa
A wreath product is a method to construct an association scheme from two association schemes. We determine the automorphism group of a wreath product. We show a known result that a…
Lovàsz's hom-counting theorem by inclusion-exclusion principle
Shoma Fujino, Makoto Matsumoto
Let be the category of finite graphs. Lovàsz (1967) shows that if holds for any , then is isomorphic to . Pultr (…
