Contributions to the Founding of the Theory of Transfinite Numbers

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. This volume contains a translation of the two very important memoirs of Georg Cantor on transfinite numbers which appeared in the Mathematische Annalen for 1895 i 1897 under the title: Beitrage zur Begrundung der transfiniten Mengenlehre. It seems to me that, since these memoirs are chiefly occupied with the investigation of the various transfinite cardinal and ordinal numbers and not with investigations belonging to what is usually described as the theory of aggregates or the theory of sets (Mengenlehre, theorie des ensembles), - the elements of the sets being real or complex numbers which are imaged as geometrical points in space of one or more dimensions, - the title given to them in this translation is more suitable.

These memoirs are the final and logically purified statement of many of the most important results of the long series of memoirs begun by Cantor in 1870.
