1. Masanobu Kaneko, Yoshinori Mizuno, Genus character L-functions of quadratic orders and class numbers, Journal of the London Mathematical Society, 10.1112/jlms.12313, 102, 1, 69-98, 2020.08, [URL], An explicit form of genus character (Formula presented.) -functions of quadratic orders is presented in full generality. As an application, we generalize a formula due to Hirzebruch and Zagier on the class number of imaginary quadratic fields expressed in term of the continued fraction expansion..
2. Masanobu Kaneko, Hirofumi Tsumura, MULTI-POLY-BERNOULLI NUMBERS AND RELATED ZETA FUNCTIONS, Nagoya Mathematical Journal, 10.1017/nmj.2017.16, 232, 19-54, 2018.12, [URL], We construct and study a certain zeta function which interpolates multi-poly-Bernoulli numbers at nonpositive integers and whose values at positive integers are linear combinations of multiple zeta values. This function can be regarded as the one to be paired up with the ξ-function defined by Arakawa and Kaneko. We show that both are closely related to the multiple zeta functions. Further we define multi-indexed poly-Bernoulli numbers, and generalize the duality formulas for poly-Bernoulli numbers by introducing more general zeta functions..

Hiroshi Yoshida, Yoshihiro Miwa, Masanobu Kaneko, Elliptic curves and Fibonacci numbers arising from Lindenmayer system with symbolic computation, APPLICABLE ALGEBRA IN ENGINEERING COMMUNICATION AND COMPUTING, 10.1007/s00200-011-0143-7, 22, 2, 147-164, 2011.03, [URL], Starting from an egg, the multicell becomes a set of cells comprising a variety of types to serve functions. This phenomenon brings us a bio-motivated Lindenmayer system. To investigate conditions for a variety of cell types, we have constructed a stochastic model over Lindenmayer systems. This model considers interactive behaviors among cells, yielding complicated polynomials. Using symbolic computation, we have derived explicit relations between cell-type diversity and cell-type ratio constraint. These relations exhibit elliptic curve-and Fibonacci number-related patterns. This is the first example of elliptic curves to appear in the Lindenmayer context. A survey of the rational points and the quadratic irrational numbers on the derived curves has revealed Fibonacci-related periodic and quasiperiodic patterns. Further we have found that in some region, there are only two elliptic curve-related periodic patterns..
