  1. Hace 5 días · Domain for Dirichlet's problem. We have two options to solve this problem: separation of variables method and sine Fourier transform. We show how both options work, starting with the latter.

  2. Hace 4 días · There are times that it might not be so simple to find the Green's function in the simple closed form that we have seen so far. However, there is a method for determining the Green's functions of Sturm-Liouville boundary value problems in the form of an eigenfunction expansion.

  3. Hace 2 días · Dirichlet's theorem is a theorem in number theory, which states that for any two coprime positive integers \(a\) and \(d\), there exists an infinite amount of positive integers \(n\) for which \(an + d \) is a prime number.

  4. Hace 4 días · Russell Herman. University of North Carolina Wilmington. We begin with the particular solution (8.13) of our nonhomogeneous differential equation (8.3). This can be combined with the general solution of the homogeneous problem to give the general solution of the nonhomogeneous differential equation:

  5. Hace 3 días · Dirichlet L-series and other number fields. The Riemann hypothesis can be generalized by replacing the Riemann zeta function by the formally similar, but much more general, global L-functions. In this broader setting, one expects the non-trivial zeros of the global L-functions to have real part 1/2.

  6. 2 de may. de 2024 · Dirichlet series and Laplace transform. Let ∑n=1∞ an ns ∑ n = 1 ∞ a n n s be a Dirichlet series. It can be represented as a Riemann-Stieltjes integral as follows: ∑n=1∞ an ns =∫∞ 1 1 xsd(A(x)) = limx→∞ A(x) xs + s∫∞ 1 A(x) xs+1 dx ∑ n = 1 ∞ a n n s = ∫ 1 ∞ 1 x s d ( A ( x)) = lim x → ∞ A ( x) x s ...
