And since we have already verified the Riemann-Lebesgue lemma to be true for step functions we have that $\displaystyle{\lim_{n \to \infty} \int_I s_n(t)

60], Il lemma di Riemann-Lebesgue afferma che l'integrale della trasformata di una funzione tende ad annullarsi al crescere del numero di oscillazioni della funzione. In matematica , in particolare nell' analisi armonica , il lemma di Riemann-Lebesgue , il cui nome è dovuto a Bernhard Riemann e Henri Lebesgue , è un teorema che afferma che la trasformata di Fourier o Laplace di una funzione Riemann-Lebesgue lemma would hold. In fact Riemann integrable functions can be approximated by step functions (i.e. piece-wise constant functions) so the R-L lemma holds for such functions. Yet the name of the Lemma contains Lebesgue because he showed that it holds for Lebesgue integrable functions.

I matematik , den Riemann-Lebesgue lemma , uppkallad efter Bernhard Riemann och Henri Lebesgue , anges att Fouriertransformen eller Laplace transform av Riemann-Lebesgue Lemma: Surhone, Lambert M.: Amazon.se: Books. Applying the Riemann-Lebesgue Lemma, we see that (̂ f(k)(n))n∈Z converges to 0 as |n|→∞. Hence ( ˆf(n))n∈Z is o( 1. |n|k ). 2.
