Martin Aigner
Martin Aigner (born February 28, 1942 in Linz) is an Austrian mathematician and professor at Freie Universität Berlin since 1974 with interests in combinatorial mathematics and graph theory. He received his Ph.D from the University of Vienna. His book '' Proofs from THE BOOK'' (co-written with Günter M. Ziegler) has been translated into 12 languages. He is a recipient of a 1996 Lester R. Ford Award from the Mathematical Association of America for his expository article '' Turán's Graph Theorem''. In 2018, Aigner received the Leroy P. Steele Prize The Leroy P. Steele Prizes are awarded every year by the American Mathematical Society, for distinguished research work and writing in the field of mathematics. Since 1993, there has been a formal division into three categories. The prizes have b ... for Mathematical Exposition (jointly with Günter M. Ziegler).

Linz
Linz ( , ; cs, Linec) is the capital of Upper Austria and third-largest city in Austria. In the north of the country, it is on the Danube south of the Czech border. In 2018, the population was 204,846. In 2009, it was a European Capital of Culture. Geography Linz is in the centre of Europe, lying on the Paris–Budapest west–east axis and the Malmö–Trieste north–south axis. The Danube is the main tourism and transport connection that runs through the city. Approximately 29.27% of the city's wide area is grassland. A further 17.95% are covered with forest. All the rest areas fall on water (6.39%), traffic areas and land. Districts Since January 2014 the city has been divided into 16 statistical districts: Before 2014 Linz was divided into nine districts and 36 statistical quarters. They were: #Ebelsberg #Innenstadt: Altstadtviertel, Rathausviertel, Kaplanhofviertel, Neustadtviertel, Volksgartenviertel, Römerberg-Margarethen #Kleinmünchen: Kleinmünchen, N ...

Turán's Theorem
In graph theory, Turán's theorem bounds the number of edges that can be included in an undirected graph that does not have a complete subgraph of a given size. It is one of the central results of extremal graph theory, an area studying the largest or smallest graphs with given properties, and is a special case of the forbidden subgraph problem on the maximum number of edges in a graph that does not have a given subgraph. An example of an n- vertex graph that does not contain any (r+1)-vertex clique K_ may be formed by partitioning the set of n vertices into r parts of equal or nearly equal size, and connecting two vertices by an edge whenever they belong to two different parts. The resulting graph is the Turán graph T(n,r). Turán's theorem states that the Turán graph has the largest number of edges among all -free -vertex graphs. Turán's theorem, and the Turán graphs giving its extreme case, were first described and studied by Hungarian mathematician Pál Turán in 1941. ...

Cartellverband Members
The Union of Catholic German Student Fraternities (german: Cartellverband der katholischen deutschen Studentenverbindungen or ''Cartellverband'' (CV)) is a German umbrella organization of Catholic male student fraternities (Studentenverbindung). History Foundation During the period of 19th century in Germany called the Kulturkampf, the Prussian state tried to reduce the influence of the Catholic Church. As a result of this, many Catholic organizations were founded in order to withstand this pressure by forming a single front. Catholic students of several universities in Germany, Austria and Switzerland formed Catholic fraternities. These Catholic fraternities were the successors of informal Catholic clubs, founded by students of theology. They were formed according to the historic examples of the already existing fraternities, like wearing couleur, rules of behaviour, lifelong membership and democratic organization, but added as main principle the foundation upon the Catholi ...

Academic Staff Of The Free University Of Berlin
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientists From Linz
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

1942 Births
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 '' Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.
