Alexander Osipovich Gelfond (russian: Алекса́ндр О́сипович Ге́льфонд; 24 October 1906 – 7 November 1968) was a Soviet mathematician. Gelfond's theorem, also known as the Gelfond-Schneider theorem is named after him. Biography Alexander Gelfond was born in Saint Petersburg, Russian Empire, the son of a professional physician and amateur philosopher Osip Gelfond. He entered the Moscow State University in 1924, started his postgraduate studies there in 1927 and obtained his PhD in 1930. His advisors were Aleksandr Khinchin and Vyacheslav Stepanov. In 1930 he stayed for five months in Germany (in Berlin and Göttingen) where he worked with Edmund Landau, Carl Ludwig Siegel and David Hilbert. In 1931 he started teaching as a Professor at the Moscow State University and worked there until the last day of his life. Since 1933 he also worked at the Steklov Institute of Mathematics. In 1939 he was elected a Corresponding member of the Academy of Sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Gelfond
Michael Gelfond is a Professor in Computer Sciences at Texas Tech University in the United States. He received a degree in mathematics from the Steklov Institute of Mathematics in Russia in 1974 and emigrated to the United States in 1978. Gelfond's research interests are in the areas of computational logic and knowledge representation. He is a Fellow of the Association for the Advancement of Artificial Intelligence, and an Area Editor (in Knowledge Representation and Nonmonotonic Reasoning) of the journal ''Theory and Practice of Logic Programming''. He, together with Vladimir Lifschitz, defined stable model semantics for logic programs, which later became the theoretical foundation for Answer Set Programming Answer set programming (ASP) is a form of declarative programming oriented towards difficult (primarily NP-hard) search problems. It is based on the stable model (answer set) semantics of logic programming. In ASP, search problems are reduced ...,Victor Marek and Mirosla ...

Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elepha ...

Yiddish Language
Yiddish (, or , ''yidish'' or ''idish'', , ; , ''Yidish-Taytsh'', ) is a West Germanic language historically spoken by Ashkenazi Jews. It originated during the 9th century in Central Europe, providing the nascent Ashkenazi community with a vernacular based on High German fused with many elements taken from Hebrew (notably Mishnaic) and to some extent Aramaic. Most varieties of Yiddish include elements of Slavic languages and the vocabulary contains traces of Romance languages.Aram Yardumian"A Tale of Two Hypotheses: Genetics and the Ethnogenesis of Ashkenazi Jewry".University of Pennsylvania. 2013. Yiddish is primarily written in the Hebrew alphabet. Prior to World War II, its worldwide peak was 11 million, with the number of speakers in the United States and Canada then totaling 150,000. Eighty-five percent of the approximately six million Jews who were murdered in the Holocaust were Yiddish speakers, Solomon Birnbaum, ''Grammatik der jiddischen Sprache'' (4., erg. Aufl., Ham ...
