Clean and fine. <br/><br/><em>First printing of this importent paper in which Féjer states the "Summation Theorem" that bears his name."Fejér’s main works deal with harmonic analysis. His classic theorem on C 1 summability of trigonometric Fourier series 1900 not only gave a new direction to the theory of orthogonal expansions but also through significant applications became a starting point for the modern general theory of divergent series and singular integrals. Through a Tauberian theorem of G. H. Hardy’s the convergence theory of Fourier series was considerably affected by Fejér’s theorem as well; it is closely connected with Weierstrass’ approximation theorems and with the more advanced theory of power series and harmonics potential theory and makes possible a number of analogues for related series such as Laplace series."DSB. </em> unknown

Clean and fine. <br/><br/><em>First printing this importent paper in which Ivory introduces his well-known theorem which bears his name. It states that the attraction of an ellipsoid upon a point exterior to it is dependent upon the attraction of another ellipsoid upon a point interior to it."In 1809 J. Ivory proved the three-dimensional version of this theorem by straightforward calculation and by using an appropriate parametrization. This theorem holds in the n-dimensional Euclidean space n > 1. It has been shown that it is also true in the pseudo-Euclidean plane Minkowski" H. Stachel."Ivory's scientific reputation for which he was awarded many honours during his lifetime including knighthood of the Order of the Guelphs Civil Division 1831 was founded on the ability to understand and comment the work of the French analysts rather than any great originality of his own.Ivory's work conducted with great industry over a long period helped to foster in England a new interest in the application of analysis to physical problems."

It resisted the attempts of able mathematicians for over a century and when it was successfully proved in 1976 the ‘computer proof’ was controversial: it did not allow scrutiny in the conventional way. At the height of his influence in 1878 Arthur Cayley had drawn attention to the problem at a meeting of the London Mathematical Society and it was duly ‘announced’ in print. the paper offered. He made a short contribution himself and he encouraged the young A. B. Kempe to publish a paper on the subject. Though ultimately unsuccessful the work of Cayley and Kempe in the late 1870s brought valuable insights. Francis Galton is revealed as the ‘go-between’ in suggesting Cayley publish his observations in Proceedings of the Royal Geographical Society." Tony Crilly.The Four-Colour-Theorem was proved in 1976 by Kenneth Appel and Wolfgang Haken. It was the first major mathematical theorem to be proved using a computer. </em> unknown

Clean and fine. <br/><br/><em>First appearance of this outstanding contribution to mathematics announcing his invention and developments of the ALGEBRA OF MATRICES what is now called the Cayley-Hamilton theorem for square matrices of any order. "The subject originated in a memoir of 1858 the paper offered and grew directly out of simple observations on the way in which the transformations linear of the theory of algebraic invariants are combined.a distinctive feature of these rules is that multiplication is not commutative.we get different results according to the order in which we do the multiplication. it seems about as far from anything of scientific or practical use as anything could possible be. Yet sixty seven years after Cayley's invented it HEISENBERG in 1925 recognized in the algebra of matrices exactly the tool which he neede for his revolutionary work in QUANTUM MECHANICS."Bell Men of Mathematics."It was in connection with the study of invariants under linear transformation that Cayley first introduced matrices to simplify the notation involved. Here he gave some basic notions. This was followed by his first major paper on the subject "A Memoir on the Theory of Matrices." the paper offered here.

He here gives the proof of THE FUNDAMENTAL THEOREM OF ALGEBRA called d'Alembert's theorem and later corrected by Gauss 1799.The theorem is based on these three assumptions:Every polynomial with real coefficients which is of odd order has a real root. This is a corollary of the intermediate value theorem. Every second order polynomial with complex coefficients has two complex roots. For every polynomial p with real coefficients there exists a field E in which the polynomial may be factored into linear terms.Also with an importent paper by Leonhard Euler "Mémoire sur l'Effet de la Propagation successive de la Lumiere dans l'Apparition tant des Planetes que des Cometes" Memoir on the effect of the successive propogation of light in the appeareance of both comets and planets.
