integral to a parameter with its uniform convergence (newly introduced by Weierstrass at the time). In 1904 in Leipzig, B. G. Teubner published Selivanov's monograph on the calculus of finite differences (which was also published in Russian and Czech). For Klein's encyclopedia, he wrote in 1901 an article based upon a book published in 1891 by Andrei Andreyevich Markov, a professor extraordinarius in Saint Petersburg. Markov's book was published in German translation in 1896. Selivanov published in German under the name Demetrius Seliwanoff. He published in French under the name D. Sélivanoff. For the French version of Klein's encyclopedia, Henri Andoyer made a 1906 translation combining the article by Selivanov on the calculus of finite differences and the article by Julius Bauschinger on interpolation from the original German version of Klein's encyclopedia.
