Designing a web-based learning support system for flow-chart proving in school geometry

Autor: Yasuo Iwanaga, Mikio Miyazaki, Keith Jones, Taro Fujita

As international research confirms, many secondary school students can find it difficult to construct mathematical proofs. In this article, we explain the pedagogical and technological underpinnings of a web-based learning support system for students

On Auslander's n-gorenstein rings

Autor: Hideo Sato, Yasuo Iwanaga

Publikováno v: Journal of Pure and Applied Algebra. (1):61-76

According to Auslander, a Noetherian ring R is called n -Gorenstein for n ≥ 1 if in a minimal injective resolution 0 → R R → E 0 → E 1 → … → E n →, …, the flat dimension of each E i is at most i for i = 0, 1, …, n − 1. We prove
