Magnitude of fourier coefficients and degree of approximation by riemann sums
Numerical Functional Analysis and Optimization, 1991We compare rates of decay of the cosine Fourier coefficients of a 2φ-periodic function f with that of Riemann sum of f over [0, 2φ] minus .

Unsteady MHD Couette Flows in an Annuli: The Riemann-Sum Approximation Approach
Journal of the Physical Society of Japan, 2010The unsteady MHD Couette flow of a viscous incompressible electrically conducting fluid between two concentric horizontal cylinders of infinite length have been analysed when the outer cylinder has been set into uniform accelerated motion. A unified closed form expressions are derived corresponding to the cases of the magnetic field fixed relative to ...

Cauchy and Riemann Sums, Factorials, Ramanujan Numbers and Their Approximations
2016After a short recall of the basic asymptotic relations “big O” and “small o”, we consider the Cauchy sums of the form \(\displaystyle \sum _{a\le k 0\); in the case where \(\alpha =1\) these are strictly related to the celebrated Riemann sums. After having learned how to approximate such sums, we apply the results to the approximation of sums of the ...
