NettetThis is a simple consequence of the identity theorem. Bump functions are often used as mollifiers, as smooth cutoff functions, and to form smooth partitions of unity. They are … NettetThis is because we expressed ξ n f ^ ( ξ) as a Fourier transform of an integrable function. We deduce that f ^ decays at least like ξ − n. Conversely, a good decay of Fourier transform used with inverse Fourier transform and differentiation under the integral gives smoothness of the function.

NettetTo bound this function, first we use the fact that D m ϕ ^ ( ξ) = F { ( − 2 π i x) m ϕ ( x) }, where F denotes the Fourier transform F ( ψ) ( ξ) = ψ ^ ( ξ) := ∫ R ψ ( x) e − 2 π i x ξ d x. We may therefore write ξ n D m ϕ ^ ( ξ) = ξ n F { ( − 2 π i x) m ϕ ( x) } = ( 2 π i ξ) n ( 2 π i) n F { ( − 2 π i x) m ϕ ( x) }. If we next use the identity
