Hans Freudenthal (1905-1990) was once a Dutch mathematician, born in Luckenwalde, Germany. His medical actions have been of a wealthy style. Enrolling on the college of Berlin as a pupil within the Twenties, he within the footsteps of his lecturers and have become a topologist, yet with a full of life curiosity in workforce idea. After an extended trip during the realm of arithmetic, engaged on just about all matters that drew his curiosity, he grew to become towards the sensible and methodological problems with the didactics of arithmetic. the current Selecta are dedicated to Freudenthal's mathematical oeuvre. They include a range of his significant contributions, together with his primary contributions to topology resembling the root of the idea of ends (in the thesis of 1931) in addition to the advent (in 1937) of the suspension and its use in balance effects for homotopy teams of spheres. In crew concept there's paintings on topological teams (of the Nineteen Thirties) and on a variety of elements of the speculation of Lie teams, akin to a paper on automorphisms of 1941. From the later paintings of the Fifties and Nineteen Sixties, papers on geometric points of Lie idea (geometries linked to unparalleled teams, house difficulties) were incorporated. Freudenthal's versatility is additional validated by way of choices from his foundational and ancient paintings: papers on intuitionistic good judgment and topology, a paper on axiomatic geometry reappraising Hilbert's Grundlagen, and a paper summarizing his improvement of Lincos, a common ("cosmic") language.

This publication describes an invariant, l, of orientated rational homology 3-spheres that is a generalization of labor of Andrew Casson within the integer homology sphere case. enable R(X) denote the gap of conjugacy periods of representations of p(X) into SU(2). allow (W, W, F) be a Heegaard splitting of a rational homology sphere M. Then l(M) is said to be an effectively outlined intersection variety of R(W) and R(W) within R(F). The definition of this intersection quantity is a fragile job, because the areas concerned have singularities. A formulation describing how l transforms less than Dehn surgical procedure is proved. The formulation includes Alexander polynomials and Dedekind sums, and will be used to provide a slightly trouble-free evidence of the life of l. it's also proven that once M is a Z-homology sphere, l(M) determines the Rochlin invariant of M

Absolute measurable house and absolute null house are very outdated topological notions, constructed from famous evidence of descriptive set concept, topology, Borel degree conception and research. This monograph systematically develops and returns to the topological and geometrical origins of those notions. Motivating the advance of the exposition are the motion of the gang of homeomorphisms of an area on Borel measures, the Oxtoby-Ulam theorem on Lebesgue-like measures at the unit dice, and the extensions of this theorem to many different topological areas. lifestyles of uncountable absolute null house, extension of the Purves theorem and up to date advances on homeomorphic Borel chance measures at the Cantor area, are one of the issues mentioned. A short dialogue of set-theoretic effects on absolute null area is given, and a four-part appendix aids the reader with topological size concept, Hausdorff degree and Hausdorff measurement, and geometric degree concept.
