= Multipliers and centralizers (Banach spaces)
{wiki=Multipliers_and_centralizers_(Banach_spaces)}
In the context of Banach spaces and functional analysis, "multipliers" and "centralizers" refer to specific types of linear operators that act on spaces of functions or sequences, and are of interest in areas such as harmonic analysis, operator theory, and the study of functional spaces. \#\#\# Multipliers In the context of Banach spaces or spaces of functions (often within the framework of Fourier analysis), a **multiplier** is typically defined in relation to Fourier transforms or similar transforms.
