Mechanical Quadrature Method and Splitting Extrapolation for Solving Dirichlet Boundary Integral Equation of Helmholtz Equation on Polygons

Journal of Applied Mathematics, 2014
We study the numerical solution of Helmholtz equation with Dirichlet boundary condition. Based on the potential theory, the problem can be converted into a boundary integral equation.

An Efficient Quadrature Rule for Highly Oscillatory Integrals with Airy Function

Mathematics
In this work, our primary focus is on the numerical computation of highly oscillatory integrals involving the Airy function. Specifically, we address integrals of the form ∫0bxαf(x)Ai(−ωx)dx over a finite or semi-infinite interval, where the integrand ...

Information Theory and Quadrature Rules

, 2010
Quadrature rules estimate the value of an integral when the function is given by a table of values. Every binary string defines a quadrature rule by choosing which endpoint of each interval represents the interval. The standard rules, such as Simpson's Rule, correspond to strings of low Kolmogorov complexity, making it possible to define new quadrature
