2 days ago · Bessel functions, first defined by the mathematician Daniel Bernoulli and then generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel's differential equation + + = for an arbitrary complex number, which represents the order of the Bessel function.
3 days ago · If parameters μ n and μ k are chosen in a way to annihilate the right-hand side of Eq.\eqref{EqOrtho.2}, we get orthogonality of Bessel's functions. We consider three important cases of boundary conditions for which Bessel's functions are orthogonal.
3 days ago · Bessel generating functions. Peter Andreas Hansen (1795--1874), a German astronomer, was the first who discovered in 1843 the generating function for the Bessel functions of the first kind: ex(z−1/z)/2 = ∑n=−∞∞ znJn(x) e x ( z − 1 / z) / 2 = ∑ n = − ∞ ∞ z n J n ( x)
3 days ago · A Bessel equation is a special case of a confluent hypergeometric equation. The Bessel function of the first kind of order ν: Jν(x) =∑k≥0 (−1)k k!Γ(k + ν + 1)(x 2)2k+ν, J ν ( x) = ∑ k ≥ 0 ( − 1) k k! Γ ( k + ν + 1) ( x 2) 2 k + ν, where Γ(z) =∫∞ 0 xz−1e−xdx Γ ( z) = ∫ 0 ∞ x z − 1 e − x d x is the gamma ...

4 days ago · Truth is a very different thing from fact; it is the loving contact of the soul with spiritual fact, vital and potent. It does not work in the soul independently of all faculty or qualification there for setting it forth or defending it. Truth in the inward parts is a power, not an opinion. George Macdonald, p. 603.
