First printing of three important papers by Brouwer. In "Zur Invarianz des n-dimensionalen Gebiets" Brouwer introduced his "Invariance of domain" which is a theorem in topology about homeomorphic subsets of Euclidean space."The existence of one-to-one correspondences between numerical spaces Rn for different n, shown by Cantor, together with Peano's subsequent example (1890) of a continuous mapping of the unit segment onto the square, had induced mathematicians to conjecture that topological mappings of numerical spaces Rn would preserve the number n (dimension). In 1910 Brouwer proved this conjecture for arbitrary n." (DSB).
