Witold Kazimierz Roter (September 20, 1932 â June 19, 2015, in Wrocà Âaw.) was a mathematician, of the Polish School of Mathematics, expert in differential geometry.
Witold Kazimierz Roter was born on September 20, 1932, in Zabrze-Pawà Âów. He attended primary and then secondary school in Zabrze, and next, he studied mathematics at the University of Wrocà Âaw â 1st degree studies in 1950âÂÂ1953 and 2nd degree studies (extramural) in 1955âÂÂ1958. In 1958 he obtained a master's degree in mathematics. In 1953, after completing the first cycle of studies, he was ordered to work as a teacher at the Nowa Ruda Primary School No. 1 and in the Secondary School. He worked there until 1961. In the same year, he was accepted as a senior assistant at the Faculty of Mathematics, Physics and Chemistry of the University of Wrocà Âaw.
Witold Kazimierz Roter died on June 19, 2015, in Wrocà Âaw. He is buried at Osobowice Cemetery in Wrocà Âaw
In 1963 at the Wrocà Âaw University he defended his doctoral thesis "On certain properties of recursive and weak-recursive spaces" written under the supervision of Wà Âadysà Âaw à Âlebodzià Âski, and in 1974 he obtained his habilitation. He was awarded the title of professor of mathematical sciences in 1992. He was an employee of the Mathematical Institute of the University of Wrocà Âaw, where he was deputy director of the Mathematical Institute, vice-dean of the Faculty of Mathematics, Physics and Chemistry, and for many years he headed the Department of Geometry, and the Institute of Mathematics of the Wrocà Âaw University of Technology.
In the years 1989âÂÂ1991 he was the president of the Wrocà Âaw Branch of Polish Mathematical Society, and in the years 1996âÂÂ2004 the president of the Scholarship Foundation of Wrocà Âaw Mathematicians.
Andrzej Derdià Âski writes about his contribution to the development of differential geometry. Since 1961 he published more than 36 scientific papers. A summary of his most important works can be found in Mathematical Reviews and Zentralblatt fur Mathematik.
He was awarded the Gold Cross of Merit and the Knight's Cross of the Order of Polonia Restituta. In 1983 he was awarded the Tadeusz Waà ¼ewski Prize
June 2, 2017, at the Secondary School im. Henryk Sienkiewicz in Nowa Ruda, a plaque dedicated to the professor was unveiled, and an obelisk with a commemorative plaque was unveiled in the square at the Market Square, which was named after Roter.
