Gesammelte Abhandlungen I - Collected Works I : Mit Einem Geleitwort von Karl Popper / With a Foreword by Harl Popper - Band 1 / Volume 1 (Softcover reprint of the original 1st ed. 1995)

Like Descartes and Pascal, Hans Hahn (1879-1934) was both an eminent mathematician and a highly influential philosopher.

He founded the Vienna Circle and was the teacher of both Kurt Godel and Karl Popper.

His seminal contributions to functional analysis and general topology had a huge impact on the development of modern analysis.

Hahn's passionate interest in the foundations of mathematics, vividly described in Sir Karl Popper's foreword (which became his last essay), had a decisive influence upon Godel.

Like Freud, Musil and Schonberg, Hahn became a pivotal figure in the feverish intellectual climate of Vienna between the two wars. Volume 1: The first volume of Hahn's Collected Works contains his path-breaking contributions to functional analysis, the theory of curves, and ordered groups.

These papers are commented on by Harro Heuser, Hans Sagan, and Laszlo Fuchs.

Volume 2: The second volume deals with functional analysis, real analysis and hydrodynamics.

The commentaries are written by Wilhelm Frank, Davis Preiss, and Alfred Kluwick. Volume 3: In the third volume, Hahn's writings on harmonic analysis, measure and integration, complex analysis and philosophy are collected and commented on by Jean-Pierre Kahane, Heinz Bauer, Ludger Kaup, and Christian Thiel.

This volume also contains excerpts of Hahn's letters and accounts by his students and colleagues.
