| 研究成果の概要 |
超離散一次分数変換を差分作用素とした有界開区間上のトロピカル値分布論の確立などLaine, Korhonen, Heittokangas, Y-Y. Zhengと複素関数方程式についての知見を得、Gundersen, Steinmetzと共同して有理型函数の5対複素数共有に関する未解決問題を肯定的に解決した。石崎, Wen, Li, J-H. Zhengも加わり指数函数多項式の零点分布、差分版radicalによるMason's theoremの類似、有理型函数の差分商評価の精密化で最良の評価を導いた。更にLinと値の共有概念の差分化に関しても最良の結果を得るなど当初目的に叶う研究成果を上げた。
