= Riesz projector
{wiki=Riesz_projector}
The Riesz projector is a mathematical concept that arises in functional analysis, particularly in the context of spectral theory of linear operators. It is named after the Hungarian mathematician Frigyes Riesz. \#\#\# Definition Given a bounded linear operator \\( T \\) on a Banach space, the Riesz projector associated with \\( T \\) is a projection operator that projects onto the eigenspace corresponding to a specific point in the spectrum of \\( T \\).
