Machine-translated · View original
A lab that studies information theory and operator theory.

AboutAbout the lab
The mathematics of information entropy and operators.
Yanagida Lab studies information theory and operator theory.
Its research topics are the foundations of information entropy and its applications, and operator inequalities and their applications.
Professor Masahiro Yanagida studied linear operators on Hilbert spaces and has since also taken up research on information entropy and its applications.
Key terms
- Information theory
- A field that uses mathematics to study the amount of information and how it is conveyed. Information entropy is the basic idea for measuring the amount of information.
- Operator theory
- A field that uses mathematics to study the properties of operators, which are mappings that turn functions and similar objects into something else.
- Operator inequality
- An inequality that expresses the order relation between operators. It extends inequalities between numbers to operators.
ResearchResearch themes
