The application of quadratic forms in an infinity of variables to boundary problems in partial differential equations
Published online by Cambridge University Press: 24 October 2008
Extract
The object of this paper is to find the characteristic functions and the characteristic numbers of the partial differential equation
valid in a domain G, and where on Γ, the boundary of G. The method employed is to transform two quadratic forms to their common self-conjugate “triangle“ of reference. The solution to the problem is given by this method in a simple manner, without the use of the integral equation theory, or the use of minimal sequences.
