The dirichlet function

WebIn mathematical analysis, the Dirichlet kernel, named after the German mathematician Peter Gustav Lejeune Dirichlet, is the collection of periodic functions defined as where n is any nonnegative integer. The kernel functions are periodic with period . WebDirichlet 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 …

WebWhen imposed on an ordinary or a partial differential equation, it specifies the values that a solution needs to take along the boundary of the domain. In finite element method (FEM) analysis, essential or Dirichlet boundary condition is defined by weighted-integral form of a differential equation. [2] The Dirichlet function is not Riemann-integrable on any segment of R whereas it is bounded because the set of its discontinuity points is not negligible (for the Lebesgue measure). The Dirichlet function provides a counterexample showing that the monotone convergence theorem is not true in the context of … See more In mathematics, the Dirichlet function is the indicator function 1Q or $${\displaystyle \mathbf {1} _{\mathbb {Q} }}$$ of the set of rational numbers Q, i.e. 1Q(x) = 1 if x is a rational number and 1Q(x) = 0 if x is not a rational number (i.e. … See more • Thomae's function, a variation that is discontinuous only at the rational numbers See more • The Dirichlet function is nowhere continuous.
