Excerpt from Multilinear Functions of Direction: And Their Uses in Differential GeometryThe theory of multilinear functions does not merely coordinate. It affords simple proofs of the relations between the cubic functions of Laguerre and Barboux and of formulae 7851, 7352) for the twist of a family of surfaces, and it leads naturally to expressions (7241) for the rates of change of the two principal curvatures of a variable member of a family ...

Excerpt from Jacobian Elliptic FunctionsThe design of this treatise will now be intelligible. There are three divisions of the subject, first the direct theory of functions with simple poles derived from a Weierstrassian function whose periods are arbi trary, then the theory of the inverted integral and the solution of the problem of inversion, and lastly the fertile theory of the classical system. To the writer the order of exposition is almo...

Excerpt from Prolegomena to Analytical Geometry in Anisotropic Euclidean Space of Three DimensionsHence the bewilderment of the man in the street, who does not suspect, for example, that when an event is described as 'a point in a four-dimensional space where time is imaginary', five terms with which he is familiar are being used with technical meanings that he does not know.About the PublisherForgotten Books publishes hundreds of thousands of...
