Cauchy Principal Value Contour Integral with Applications [PDF]
Cauchy principal value is a standard method applied in mathematical applications by which an improper, and possibly divergent, integral is measured in a balanced way around singularities or at infinity.

Spline approximation for Cauchy principal value integrals [PDF]
The author considers the problem of numerical evaluation of Cauchy principal value integrals of the form \(I(f^{(k)};y)=\oint^{b}_{a}w(x)f^{(k)}(x)/(x-y)dx\quad (k=0,1,...).\) She examines quadrature rules of the form: \(I(f^{(k)};y)\approx I_ n(f^{(k)};y)=\sum^{n}_{i=0}w_ i^{(k)}(y)f(x_ i),\) where \(a=x_ ...

Numerical evaluation of a generalized Cauchy principal value [PDF]
Summary: A method is presented for the evaluation of a generalized Cauchy principal value of an improper integral. The integral is transformed into a Riemann integral which is evaluated using Romberg integration. This method is very convenient for computational purposes.

On quadrature for Cauchy principal value integrals of oscillatory functions [PDF]
Based on a quadrature suggested by \textit{G. E. Okecha} [Math. Comput. 49, 259--268 (1987; Zbl 0634.65013)] the authors deal with the numerical evaluation of Cauchy principal value integrals \[ H^\omega(g; t)= \lim_{\varepsilon\to 0^+}\,\int_{| x-t|\geq \varepsilon} {g(x)\over x- t} e^{i\omega x} \,dx\qquad (t\in (-1,1)).

A sinc-Hunter quadrature rule for Cauchy principal value integrals [PDF]
A Sinc function approach is used to derive a new Hunter type quadrature rule for the evaluation of Cauchy principal value integrals of certain analytic functions. Integration over a general arc in the complex plane is considered. Special treatment is given to integrals over the interval
