The generalization of Shanks' $e$-transformation to double series is discussed and a class of nonlinear transformations, the $\lbrack A/S \rbrack_R$ transformations ...

An elementary transformation formula is derived, allowing double integrals of the type introduced by F. Beukers to be reduced, and new ones to be constructed. Journal Information The Monthly publishes ...

Studies properties and solutions of partial differential equations. Covers methods of characteristics, well-posedness, wave, heat and Laplace equations, Green's functions, and related integral ...
