A collection of 8 offprints on geometry and number theory German imprints

Germany 1890-1905 4to & 8vo. Ueber die Bedingungen, unter welchen zwei quadratische Formen mit rationalen Coefficienten in einander rational transformit werden können, containing the first instance of the "Hasse" or "local-global" principle, 22pp., unbound offprint, [1890]; Über periodische Approximationen algrebraischer Zahlen, "...Minkowski also showed that, for his criterion, periodicity occurs in only a small number of cases, which he characterized completely" [DSB], 16½pp., original wrappers, [1902]; Allgemeine Lehrsätze über die convexen Polyeder, "entirely Minkowski showed that a convex polyhedron having a given number m of faces is determined by the areas and directions of the faces, a theorem that he generalized to convex surfaces by passage to the limit" [DSB], 22pp., original wrappers, 1897; and 5 others by the same. Very Good Original Wraps (Item ID: 0000119)


These offpirnts are from the library of German mathematician Otto Ludwig Hölder. "Otto Hölder worked on the convergence of Fourier series in 1884 he discovered the inequality now named after him. He became interested in group theory through Kronecker and Klein and proved the uniqueness of the factor groups in a composition series."( J J O'Connor and E F Robertson, History of Mathematics St. Andrews, Scotland).
