Assistant Professor
Profile
私の主な研究対象は,モックモジュラー形式と呼ばれる関数です.これはRamanujanに起源を持つ非常に古典的な対象ですが,21世紀に入り,保型形式の観点からその重要性が明らかになって以来,現代における発展目覚ましい研究領域の一つとなっています.私は学部生の頃にこの分野に興味を持ち,これまで整数論や低次元トポロジーとの関係から,このモックモジュラー形式について,幾つかのことを明らかにしてきました. またその他に,種々のゼータ関数の零点分布や多重Bernoulli数の組合せ論など,少し趣の異なるテーマについても研究を行なっています.研究領域の細分化が進む昨今ですが,その枠にとらわれる事なく,色々なことに挑戦していきたいと思っています.また上記の研究活動を主として,いくつかの研究セミナーの運営や理学部数学科の講義(演習)も担当しています.

  • REMARKABLE RELATIONS BETWEEN THE CENTRAL BINOMIAL SERIES, EULERIAN POLYNOMIALS, AND POLY-BERNOULLI NUMBERS, LEADING TO STEPHAN’S OBSERVATION

    Bényi B., Matsusaka T.

    Publisher:Kyushu Journal of Mathematics  

    The central binomial series at negative integers are expressed as a linear combination of values of certain two polynomials. We show that one of the polynomials is a special value of the bivariate Eulerian polynomial and the other polynomial is related to the anti-diagonal sum of poly-Bernoulli numbers. As an application, we prove Stephan’s observation from 2004.

    モックテータ関数は,Ramanujan最後の手紙 (1920年) において導入されたテータ関数もどきである.2002 年,モックテータ関数の崩れた保型変換理論が発見され,その豊かな世界が明らかになって以来,「崩れた保型性」の観点から多種多様なq-級数が注目されるようになった.しかし,これらの新しいq-級数は個々独立に研究が進められ,その背後に潜む保型形式的な性質が依然として不明確なことも多いため,その一体的な理論の解明が待たれている.本研究では,トポロジーや量子不変量の観点から要請されるq-級数について,明示的な保型変換を与えることで,その統一的な枠組の解明を目指す.
