Analysis Situs (paper)

"Analysis Situs" is a significant work in the field of topology written by the French mathematician Henri Poincaré, published in 1895. In this paper, Poincaré laid the groundwork for the study of topology, which is the branch of mathematics concerned with the properties of space that are preserved under continuous transformations. In "Analysis Situs," Poincaré developed key concepts and techniques that would become fundamental to topology, such as the ideas of homology and continuity.
