Abstract
THE first part of this book (pp. 1-240) is an edition of lectures on Conies delivered by Gundelfinger within the last twenty years in the University of Tübingen and the Technical School at Darmstadt. It contains a systematic exposition of the analytical theory of Conies based on the use of general homogeneous coordinates which are so arranged that corresponding results in particular homogeneous coordinates and in ordinary Cartesian coordinates can be written down from the results obtained. It also contains an exposition of the theory of sets of Conies, including four-point and four-tangent Conics, and nets and webs of Conics. The theory is not written out with the idea of enumerating all the independent concomitant forms, but with the idea of expressing the geometrical significance of the most important ones. The appendix (pp. 240–426) contains solutions of problems on the subjects treated in the first part. Many of the problems are taken from the works of Steiner, some are original, and not a few are difficult. A very complete index is given at the end of the book.
