| Outline of Final Research Achievements |
The idea of Feynman's integral is a topic of great interest in mathematics and physics. But rigorous mathematical treatment of this integral is not enough. We defined a kind of operator-valued integration and define the path integrals.
Dirac equation is the basic equation of relativistic quantum mechanics to the fermions. For the case of space-dimension = 1, Ichinose proved the path integral for Dirac equations are represented by a scalar measure. For the case of radial Dirac equation Ichinose constructed a countably additive path space measure. But in general, for the case of space-dimension > 1, Feynman path integrals for Dirac equations are not represented by (scalar-valued) measures. We showed that the path integral for Dirac equations are represented by our vector-valued measure.
