Abstract [en]

Inspired by mathematical morphology we study generalized convexity and prove that certain subsets of Hartogs domains are convex in a generalized sense.

Abstract [en]

Hans Rådström (1919--1970) was a brilliant scientist with many ideas. The paper presents his project to define smooth functions on sets without a differentiable structure. He did not publish anything on this, but inspired several other mathematicians to do so.

Abstract [sv]

L. Zamenhof (1859--1917) författade en grammatik för jiddisch under flera år omkring 1880.  Ungefär samtidigt arbetade han på ett konstgjort språk, Lingvo universala, som var en föregångare till Lingvo internacia, senare känt som esperanto.   I artikeln jämförs jiddisch med Lingvo universala.  

Abstract [eo]

L. Zamenhof (1859--1917) verkis gramatikon de jido dum pluraj jaroj ĉirkaŭ 1880.  Proksimume samtempe li laboris pri artefarita lingvo, Lingvo universala, kiu estis antaŭiranto de Lingvo internacia, poste konata kiel  esperanto.   En la artikolo jido estas komparata kun Lingvo universala.

Abstract [en]

For several centuries following its founding in 1477, all lectures and dissertations at Uppsala University were in Latin. Then, during one century, from 1852 to 1953, several languages came into use: there was a transition from Latin to Swedish, and then to French, German, and English. In the paper this transition is illustrated by language choice in doctoral theses in mathematics and in a Nordic journal.

Abstract [en]

Werner Fenchel was a pioneer in introducing duality in convexity theory. He got his PhD in Berlin, was forced to leave Germany, moved to Denmark, and lived during almost two years in Sweden. In a private letter he explained his views on the development of duality in convexity theory and the many terms that have been used to describe it. The background for his move from Germany is sketched.
