Kotenkaisekigaku ni okeru hokanmondai to Most Powerful Unfalsified Model (MPUM)

Abstract

This review article (in Japanese) presents the essentials of exact identification. Particular attention is given to the formalization of interpolation problems involving stability- and metric constraints (e.g. the Nevanlinna and the Takagi interpolation problems) in the framework of exact identification, and the representational issues for the Most powerful Unfalsified Model arising in these applications
