= Dirichlet algebra
{wiki=Dirichlet_algebra}
A Dirichlet algebra is a type of algebra that arises in the study of Fourier series and harmonic analysis, particularly in relation to the Dirichlet problem for harmonic functions. More formally, a Dirichlet algebra is defined as a closed subalgebra of the algebra of continuous functions on a compact space, specifically one that contains all constant functions and allows for the representation of certain types of bounded harmonic functions.
