Arnold Oberschelp
Arnold Oberschelp (born February 5, 1932 in Recklinghausen ) is a German mathematician and logician and was for many years professor of logic and science in Kiel.
Life
Oberschelp studied mathematics and physics at the universities of Göttingen and Münster . In Münster he did his doctorate in mathematical logic with Hans Hermes . In 1958 he was a research assistant at the Mathematical Institute of the Technical University of Hanover . In 1961 he completed his habilitation in mathematics. In 1968 he accepted a position as a full professor for logic and science at the Christian Albrechts University in Kiel . Oberschelp has been retired since 1997 .
Arnold Oberschelp developed a general class logic in which any class can be formed without the contradictions of naive set theory. Additional axioms result from the Zermelo-Fraenkel set theory , which, however, is much more manageable in its class-logic representation than the usual predicate logic representation.
"A class logic language corresponds to the mathematical language actually used far better than a predicate logic language."
In 1962 he gave a lecture as an invited speaker at the International Congress of Mathematicians in Stockholm on classes as "primordial elements" in set theory .
From 1970 to 1976 he was chairman of the German Association for Mathematical Logic and for Basic Research in the Exact Sciences , on whose board he was from 1965 to 1978.
