Which of the following is known for his work on the decidability of algebraic groups: Anatoly Maltsev or Vladimir Levenshtein?
Vladimir Levenshtein Vladimir Iosifovich Levenshtein (Russian: Влади́мир Ио́сифович Левенште́йн ; ] ; born 1935) is a Russian scientist who has done research in information theory, error-correcting codes, and combinatorial design. Among other contributions, he is known for the Levenshtein distance and a Levenshtein algorithm, which he developed in 1965.
P-adic quantum mechanics "p"-adic quantum mechanics is a relatively recent approach to understanding the nature of fundamental physics. It is the application of p-adic analysis to quantum mechanics. The p-adic numbers are a counterintuitive arithmetic system that was discovered by the German mathematician Kurt Hensel in about 1899. The closely related adeles and ideles were introduced in the 1930s by Claude Chevalley and André Weil. Their study has now transformed into a major branch of mathematics. They were occasionally applied to the physical sciences, but it wasn't until a publication by the Russian mathematician Igor Volovich in 1987 that the subject was taken seriously. There are now hundreds of research articles on the subject, along with international journals as well.
