Outline of Final Research Achievements

In the traditional logic, deductive reasoning based on the sentential/symbolic representation has been studied. By extending the framework of the traditional logic, I investigated reasoning based on diagrammatic/graphical representations and on non-monotonic and non-deductive inference rules.
I investigated, as case studies on diagrammatic reasoning, reasoning based on Euler diagrams, Venn diagrams, correspondence tables, and mathematical graphs. I further investigated heterogeneous reasoning combining these diagrams and sentential representation.
I investigated non-monotonic reasoning in terms of linear logic. I further studied one of the major non-deductive reasoning called abduction. Furthermore, I tried to apply my results on diagrammatic and non-deductive reasoning to teaching logic and mathematics.
