The Henstock-Kurzweil approach to Young integrals with integrators in BV φ

Boonpogkrong Varayu, Tuan-Seng Chew (2006)

Mathematica Bohemica

Similarity:

In 1938, L. C. Young proved that the Moore-Pollard-Stieltjes integral ∫ a b f d g exists if f ∈ B V φ [ a , b ] , g ∈ B V ψ [ a , b ] and ∑ n = 1 ∞ φ - 1 ( 1 / n ) ψ - 1 ( 1 / n ) < ∞ . In this note we use the Henstock-Kurzweil approach to handle the above integral defined by Young.

Special finite-difference approximations of flow equations in terms of stream function, vorticity and velocity components for viscous incompressible liquid in curvilinear orthogonal coordinates

Harijs Kalis (1993)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

The Navier-Stokes equations written in general orthogonal curvilinear coordinates are reformulated with the use of the stream function, vorticity and velocity components. The resulting system id discretized on general irregular meshes and special monotone finite-difference schemes are derived.
