Nikolai Maximovich Günther (, also transliterated as Nicholas M. Gunther or N. M. Gjunter) ( – May 4, 1941) was a Russian mathematician known for his work in potential theory and in integral and partial differential equations: later studies have uncovered his contributions to the theory of Gröbner bases. He was an Invited Speaker of the ICM in 1924 at Toronto, in 1928 at Bologna, and in 1932 at Zurich. Selected publications . A large paper aimed at showing the applications of Radon integrals to problems of mathematical physics: the Mathematical Reviews review refers to a 1949 reprint published by the Chelsea Publishing Company. . , reviewed also by and by . . The second edition of the monograph , now a classical textbook in potential theory, translated from the Russian original (edition cured by V. I. Smirnov and H. L. Smolitskii), which was also translated in German as . See also Harmonic function Integral equation Radon measure Notes References Biographical and general references . The "Mathematics in the USSR during its first thirty years 1917–1947" is an opus describing the developments of Soviet mathematics during the first thirty years of its existence. It consists of several survey articles, authored by Soviet experts and reviewing briefly the contributions of Soviet mathematicians to a chosen field during the years from 1917 to 1947: it was later expanded as the two volume survey (Kurosh et al. 1959a, 1959b). . The "Mathematics in the USSR during its first forty years 1917–1957" is an opus in two volumes describing the developments of Soviet mathematics during the first forty years of its existence. This is the first volume, titled "Survey articles" and consists exactly of such kind of articles authored by Soviet experts and reviewing briefly the contributions of Soviet mathematicians to a chosen field, during the years from 1917 to 1957. . The "Mathematics in the USSR during its first forty years 1917–1957" is an opus in two volumes describing the developments of Soviet mathematics during the first forty years of its existence. This is the second volume, titled "Biobibliography" (evidently an acronym for biography and bibliography), containing a complete bibliography of works published by Soviet mathematicians during that time period, alphabetically ordered with respect to author's surname and including, when possible, brief but complete biographies of the authors. .
