| Outline of Final Research Achievements |
It was the purpose of this project to construct a theory for continuous weighted composition operators on countably infinite dimensional Hilbert spaces corresponding to Jordan normal form of square matrices. While carrying out this project, we recognized relations with order preserving operator inequalities, nonassociative algebras and hyperbolic geometry. We gave some extensions of operator inequalities of Furuta type, and discovered and proved functional inequalities between certain kind of polynomials by applying matrix inequalities. Furthermore, we gave an elementary proof by hand calculation of that the balls in arbitrary real inner product spaces are not only gyrocommutative gyrogroup but also enjoying structure of gyrovector spaces, and it shows possibility of research by elementary approach of this subject.
