History of topology Topology for many years has been one of the most exciting and influential fields of research in modern mathematics. Although its origins may be traced back several hundred years it was Poincař who gave topology wings in a classic series of articles published around the turn of the century. While the earlier history sometimes called the prehistory is also considered this volume is mainly concerned with the more recent history of topology from Poincař onwards.

Some are written by professional historians of mathematics others by historically minded mathematicians who tend to have a different viewpoint
