Masao Iri (1933–2018) was a Japanese applied mathematician and a long‑time professor at the University of Tokyo. He built a reputation in numerical analysis, especially in the theory and practice of numerical integration and mathematical optimization. His work bridged abstract analysis and computational methods used in engineering and the physical sciences.

Career and background

Iri spent most of his academic life at the University of Tokyo, where he taught, advised students and published research connecting rigorous analysis with algorithm design. General descriptions of his career and publications can be found through institutional profiles and archived pages: University of Tokyo and research summaries at other academic sites: Masao Iri profile.

Research themes and contributions

Although best known for work on numerical integration and optimization, Iri's interests covered several interrelated areas of numerical mathematics. Themes associated with his research include:

  • Numerical integration (construction and analysis of quadrature and cubature rules);
  • Algorithms for nonlinear and constrained optimization;
  • Stability and error analysis of numerical schemes;
  • Connections between continuous variational formulations and discrete computational methods.

He investigated both theoretical properties (convergence, stability, conditioning) and practical algorithmic issues (implementation and performance), helping translate mathematical insight into usable computational tools.

Applications of Iri's work appear across computational physics, engineering design and applied optimization problems, where reliable integration and efficient solvers are essential. His contributions informed later developments in numerical quadrature, constrained optimization techniques and the numerical treatment of variational problems.

Today Iri is remembered as a scholar who combined careful analysis with attention to computational practice. Readers seeking primary literature or course materials can consult university archives and specialized bibliographies for a detailed list of his publications and influence on students and collaborators.
