Arnold Oberschelp (Recklinghausen, 5 de fevereiro de 1932Heikendorf (Kiel), 31 de agosto de 2024) foi um matemático alemão, especialista em lógica. Foi professor de lógica na Universidade de Kiel.[1]

Biografia

Arnold Oberschelp estudou matemática e física na Universidade de Göttingen e na Universidade de Münster. Na Universidade de Münster obteve em dezembro de 1957 um doutorado em lógica matemática, orientado por Hans Hermes.[2][3][4][5]

Em 1958 foi nomeado investigador assistente no Instituto de Matemática da Technische Hochschule Hannover (atualmente a Universidade Gottfried Wilhelm Leibniz de Hannover ou Gottfried Wilhelm Leibniz Universität Hannover), onde obteve a habilitação em matemática em 1961.[2][6] Em 1968 aceitou sua nomeação como professor catedrático de Lógica e Epistemologia na Universidade de Kiel, onde em 1997 passou a professor emérito.[7]

Arnold Oberschelp desenvolveu uma lógica geral de classes na qual podem ser formadas classes arbitrárias sem as contradições básicas da teoria dos conjuntos. Os axiomas adicionais resultam na teoria dos conjuntos de Zermelo-Fraenkel, que é muito mais útil na representação lógica de classes do que na representação lógica de predicados habitual.[8]

Em 1962 foi palestrante convidado do Congresso Internacional de Matemáticos em Estocolmo tendo como tema as classes como elementos primordiais na teoria dos conjuntos.

De 1970 a 1976, foi presidente da Deutsche Vereinigung für mathematische Logik und für Grundlagenforschung der exakten Wissenschaften, a Associação Alemã para a Lógica Matemática e a Investigação Fundamental nas Ciências Exactas, em cuja direção serviu de 1965 a 1978.

Em setembro de 2019, recebeu a Moeda Memorial Beuth do Instituto Alemão de Normalização em reconhecimento dos seus serviços à normalização em matemática e técnicas fundamentais.[9]

Young birds select territories and look for mates in autumn and tend to be very vocal, especially males.[1][2] Due to their highly territorial behaviour, young birds frequently struggle to establish a territory unless a nearby adult dies. Males routinely engage in territorial fights.[1][2][3] Territories have been kn...
