Operator theorists are mathematicians who specialize in the study of operators on function spaces, mainly within the framework of functional analysis. This field investigates various types of linear operators, which are mappings that take one function (or vector) to another while preserving the structure of a vector space. Key areas of focus within operator theory include: 1. **Linear Operators**: Understanding how linear mappings act on function spaces, particularly Hilbert and Banach spaces.
