On the existence of tight relative 2-designs on binary Hamming association schemes
Eiichi Bannai, Etsuko Bannai, Hideo Bannai
It is known that there is a close analogy between "Euclidean t-designs vs. spherical t-designs" and "Relative t-designs in binary Hamming association schemes vs. combinatorial t-de…
A generalization of a theorem of Imai and its applications to Iwasawa theory
Yusuke Kubo, Yuichiro Taguchi
It is proved that, if is a complete discrete valuation field of mixed characteristic with residue field satisfying a mild condition, then any abelian variety over w…
Zeros of Witten zeta functions and absolute limit
Nobushige Kurokawa, Hiroyuki Ochiai
We introduce multiple versions of L-functions for Witten zeta functions. We study their algebraic and analytic properties. Especially we investigate the existence of zeros at negat…
Edgeworth expansion for the integrated Levy driven Ornstein-Uhlenbeck process
Hiroki Masuda, Nakahiro Yoshida
We verify the Edgeworth expansion of any order for the integrated ergodic Levy driven Ornstein-Uhlenbeck process, applying a Malliavin calculus with truncation over the Wiener-Pois…
Practical approach to the sign problem at finite theta-vacuum angle
Takahiro Sasaki, Hiroaki Kouno, Masanobu Yahiro
We investigate a way of circumventing the sign problem in lattice QCD simulations with a theta-vacuum term, using the PNJL model. We consider the reweighting method for the QCD Lag…
Asymptotic analysis of solutions to a gauged O(3) sigma model
Daniele Bartolucci, Youngae Lee, Chang-Shou Lin +1
We analyze an elliptic equation arising in the study of the gauged O(3) sigma model with the Chern-Simons term. In this paper, we study the asymptotic behavior of solutions and app…
