Dirichlet series with periodic coefficients

WebA Dirichlet L-series is a series of the form L_k(s,chi)=sum_(n=1)^inftychi_k(n)n^(-s), (1) where the number theoretic character chi_k(n) is an integer function with period k, are called Dirichlet L-series. These series are very important in additive number theory (they were used, for instance, to prove Dirichlet's theorem), and have a close connection with … In mathematics, a Dirichlet series is any series of the form Dirichlet series play a variety of important roles in analytic number theory. The most usually seen definition of the Riemann zeta function is a Dirichlet series, as are the Dirichlet L-functions. It is conjectured that the Selberg class of series obeys the generalized … See more Dirichlet series can be used as generating series for counting weighted sets of objects with respect to a weight which is combined multiplicatively when taking Cartesian products.

WebThe Dirichlet–Dini Criterion states that: if ƒ is 2 π –periodic, locally integrable and satisfies then (S nf ) ( x0) converges to ℓ. This implies that for any function f of any Hölder class α > 0, the Fourier series converges everywhere to f ( x ). Web1. If f satisfies the Dirichlet conditions in – T/2 < t < T/2, and is an even function, show that its Fourier series consists entirely of cosine terms; similarly, if f is an odd function show that its Fourier series consists entirely of sine terms.. 2.
