Finite-difference approximations for the first derivative, valid halfway between equidistant gridpoints, are in general much more accurate than the corresponding approximations, which are valid at ...
Uniform $\mathscr{O}(h^2)$ convergence is proved for the El-Mistikawy-Werle discretization of the problem $-\varepsilon u'' + au' + bu = f$ on (0, 1), $u(0) = A, u(1 ...
A recent study, led by Sabre Kais, Distinguished Professor of Chemistry and professor of electrical and computer engineering at Purdue University, and IBM’s Barbara Jones, used a quantum computer to ...
