Alexander Levitzki
Alexander Levitzki (Hebrew: אלכסנדר לויצקי; born 13 August 1940) is an Israeli biochemist who is a professor of biochemistry at the Hebrew University of Jerusalem. Birth and education Levitzki was born in 1940 in Palestine. He completed his M.Sc. in chemistry from the Hebrew University of Jerusalem in Israel. He received his Ph.D. in biochemistry and biophysics from the Hebrew University of Jerusalem and the Weizmann Institute of Science, in 1968. From 1968 to 1971, he was a post-doctoral fellow at the Department of Biochemistry, University of California at Berkeley in California, with Professor Daniel E. Koshland, Jr., where he worked in particular on negative cooperativity and half-of-the-sites reactivity. Contrary to the common misconception, Levitzki is not a descendant of the Hebrew Levite tribe. Academic career In 1970, Levitzki became a senior scientist at the Department of Biophysics, Weizmann Institute of Science. In 1974, he became an associate profess ...

Mischa Levitzki
Mischa Levitzki (also spelled Levitski; uk, Міша Левицький (); May 25, 1898 – January 2, 1941) was a Russian-born U.S.-based concert pianist. Levitzki was born in Kremenchuk, Ukraine (then part of the Russian Empire), to Jewish parents who were naturalised American citizens on a return trip to Ukraine. He was playing the violin at the age of three, but soon developed an interest in the piano, which he studied in Warsaw with Aleksander Michałowski before making his debut in Antwerp in 1906. In New York, his father brought him to the attention of Walter Damrosch, who obtained a scholarship for him at the Institute of Musical Art (now the Juilliard School) as a pupil of Zygmunt Stojowski, with whom he studied from 1907 to 1911. In 1913 Levitzki entered the Berlin Hochschule für Musik, where he became the youngest student of Ernst von Dohnányi and was awarded the Mendelssohn Prize in 1915. By this time he had performed throughout Europe and Scan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Levitzki
Jacob Levitzki, also known as Yaakov Levitsky ( he, יעקב לויצקי) (17 August 1904 - 25 February 1956) was an Israeli mathematician. Biography Levitzki was born in 1904 in the Russian Empire and emigrated to then Ottoman-ruled Palestine in 1912. After completing his studies at the Herzliya Gymnasia, he travelled to Germany and, in 1929, obtained a doctorate in mathematics from the University of Göttingen under the supervision of Emmy Noether. In 1931, after two years at Yale University, in New Haven, Connecticut, Levitzki returned to Palestine to join the faculty at the Hebrew University of Jerusalem. Awards Levitzki together with Shimshon Amitsur, who had been one of his students at the Hebrew University, were each awarded the Israel Prize in exact sciences in 1953, the inaugural year of the prize, for their work on the laws of noncommutative rings. Levitzki's son Alexander Levitzki, a recipient of the Israel Prize in 1990, in life sciences, established the Levitzki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levitzky's Theorem
In mathematics, more specifically ring theory and the theory of nil ideals, Levitzky's theorem, named after Jacob Levitzki, states that in a right Noetherian ring, every nil one-sided ideal is necessarily nilpotent. Levitzky's theorem is one of the many results suggesting the veracity of the Köthe conjecture, and indeed provided a solution to one of Köthe's questions as described in . The result was originally submitted in 1939 as , and a particularly simple proof was given in . Proof This is Utumi's argument as it appears in ;Lemma Assume that ''R'' satisfies the ascending chain condition on annihilators of the form \ where ''a'' is in ''R''. Then # Any nil one-sided ideal is contained in the lower nil radical Nil*(''R''); # Every nonzero nil right ideal contains a nonzero nilpotent right ideal. # Every nonzero nil left ideal contains a nonzero nilpotent left ideal. ;Levitzki's Theorem Let ''R'' be a right Noetherian ring. Then every nil one-sided ideal of ''R'' is nil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hopkins–Levitzki Theorem
In the branch of abstract algebra called ring theory, the Akizuki–Hopkins–Levitzki theorem connects the descending chain condition and ascending chain condition in Module (mathematics), modules over semiprimary rings. A ring ''R'' (with 1) is called semiprimary if ''R''/''J''(''R'') is semisimple algebra, semisimple and ''J''(''R'') is a nilpotent ideal, where ''J''(''R'') denotes the Jacobson radical. The theorem states that if ''R'' is a semiprimary ring and ''M'' is an ''R'' module, the three module conditions noetherian module, Noetherian, artinian module, Artinian and "has a composition series" are equivalent. Without the semiprimary condition, the only true implication is that if ''M'' has a composition series, then ''M'' is both Noetherian and Artinian. The theorem takes its current form from a paper by Charles Hopkins and a paper by Jacob Levitzki, both in 1939. For this reason it is often cited as the Hopkins–Levitzki theorem.

Radical Of A Ring
In ring theory, a branch of mathematics, a radical of a ring is an ideal of "not-good" elements of the ring. The first example of a radical was the nilradical introduced by , based on a suggestion of . In the next few years several other radicals were discovered, of which the most important example is the Jacobson radical. The general theory of radicals was defined independently by and . Definitions In the theory of radicals, rings are usually assumed to be associative, but need not be commutative and need not have a multiplicative identity. In particular, every ideal in a ring is also a ring. A radical class (also called radical property or just radical) is a class σ of rings possibly without identities, such that: # the homomorphic image of a ring in σ is also in σ # every ring ''R'' contains an ideal ''S''(''R'') in σ that contains every other ideal of ''R'' that is in σ # ''S''(''R''/''S''(''R'')) = 0. The ideal ''S''(''R'') is called the radical, or σ-ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

East Slavic-language Surnames
East or Orient is one of the four cardinal directions or points of the compass. It is the opposite direction from west and is the direction from which the Sun rises on the Earth. Etymology As in other languages, the word is formed from the fact that east is the direction where the Sun rises: ''east'' comes from Middle English ''est'', from Old English ''ēast'', which itself comes from the Proto-Germanic *''aus-to-'' or *''austra-'' "east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or "dawn", cognate with Old High German ''*ōstar'' "to the east", Latin ''aurora'' 'dawn', and Greek ''ēōs'' 'dawn, east'. Examples of the same formation in other languages include Latin oriens 'east, sunrise' from orior 'to rise, to originate', Greek ανατολή anatolé 'east' from ἀνατέλλω 'to rise' and Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine'.

Surnames Of Jewish Origin
In some cultures, a surname, family name, or last name is the portion of one's personal name that indicates one's family, tribe or community. Practices vary by culture. The family name may be placed at either the start of a person's full name, as the forename, or at the end; the number of surnames given to an individual also varies. As the surname indicates genetic inheritance, all members of a family unit may have identical surnames or there may be variations; for example, a woman might marry and have a child, but later remarry and have another child by a different father, and as such both children could have different surnames. It is common to see two or more words in a surname, such as in compound surnames. Compound surnames can be composed of separate names, such as in traditional Spanish culture, they can be hyphenated together, or may contain prefixes. Using names has been documented in even the oldest historical records. Examples of surnames are documented in the 11th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levite Surnames
Levites (or Levi) (, he, ''Lǝvīyyīm'') are Jewish males who claim patrilineal descent from the Tribe of Levi. The Tribe of Levi descended from Levi, the third son of Jacob and Leah. The surname ''Halevi'', which consists of the Hebrew definite article "" ''Ha-'' ("the") plus ''Levi'' (Levite) is not conclusive regarding being a Levite; a titular use of HaLevi indicates being a Levite. The daughter of a Levite is a " ''Bat Levi''" (''Bat'' being Hebrew for "daughter"). The Tribe of Levi served particular religious duties for the Israelites and had political (administering cities of refuge) and educational responsibilities as well. In return, the landed tribes were expected to support the Levites with a tithe (), particularly the tithe known as the First tithe, ''ma'aser rishon''. The Kohanim, a subset of the Levites, were the priests, who performed the work of holiness in the Temple. The Levites, referring to those who were not Kohanim, were specifically assigned to * singi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
