abstract: In mathematics, more specifically algebraic topology, the fundamental group (defined by Henri Poincaré in his article Analysis Situs, published in 1895) is a group associated to any given pointed topological space that provides a way of determining when two paths, starting and ending at a fixed base point, can be continuously deformed into each other. Intuitively, it records information about the basic shape, or holes, of the topological space.
