If so, is it also the case for the Lebesgue-Stieltjes integral and the stochastic integral? Mon Dec 31 Unlimited random practice problems and answers with built-in Step-by-step solutions. The best simple existence theorem states that if f is continuous and g is of bounded variation on [ ab ], then the integral exists.

Volante Mar 18 at The Mathematics stielfjes Games of Strategy: Hildebrandt calls it the Pollard—Moore—Stieltjes integral. In this theorem, the integral is considered with respect to a spectral family of projections.

The Riemann—Stieltjes integral also appears in the formulation of the spectral theorem for non-compact self-adjoint or more generally, normal operators in a Hilbert space. In general, the integral is not well-defined if f and g share any points of discontinuitybut this sufficient condition is not necessary.

In mathematicsthe Riemann—Stieltjes integral is a generalization of the Riemann integralnamed after Bernhard Riemann and Thomas Joannes Stieltjes. Nagy for details.

Collection of teaching and learning tools built by Wolfram education experts: Rudinpages — The Riemann—Stieltjes integral can be efficiently handled using an appropriate generalization of Darboux sums.

If improper Riemann—Stieltjes integrals are allowed, the Lebesgue integral is not strictly more general than the Riemann—Stieltjes integral.

If the sum tends to a fixed number asthen is called the Stieltjes integral, or sometimes the Riemann-Stieltjes integral. If and have a common point of discontinuity, then the integral does not exist.
