Southwell's relaxation methods were inspired by this classical mechanical analogy. He interpreted the Poisson DE –V*u = f(x,y) as “governing the small transverse displacement of a transversely loaded membrane” (Southwell [46, $38]), ...

Since its original publication in 1940, this book has been revised and modernized several times, most notably in 1948 (second edition) and in 1967 (third edition).
This volume provides a case study in scientific computing?the art of utilizing physical intuition, mathematical theorems and algorithms, and modern computer technology to construct and explore realistic models of problems arising in the ...
The book focuses on various aspects of the numerical solution of elliptic boundary value problems.
Leverrier's epoch is 1850 ; for T he chooses 250 years , and he computes the new elements for 1600 , 2100 , 2350. The practical merit of the procedure is obvious , but G. W. Hill [ 4 ] remarks that , though the two sets of formulas ...
The industrial and military applications of atomic energy have stimulated much mathematical research in neutron transport theory.
Trends in Lattice Theory
The present book presents the developments from that time to the first printing of this book. This third edition includes corrections made by the authors.
