Pierre Rosenstiehl
Pierre Rosenstiehl (5 December 1933 – 28 October 2020) was a French mathematician recognized for his work in graph theory, planar graphs, and graph drawing. The Fraysseix-Rosenstiehl's planarity criterion is at the origin of the left-right planarity algorithm implemented iPigalesoftware, which is considered the fastest implemented planarity testing algorithm. Rosenstiehl was directeur d’études at the École des Hautes Études en Sciences Sociales in Paris, before his retirement. He was a founding co-editor in chief of the European Journal of Combinatorics.. Rosenstiehl, Giuseppe Di Battista, Peter Eades and Roberto Tamassia organized in 1992 at Marino (Italy) a meeting devoted to graph drawing which initiated a long series of international conferences, the International Symposia on Graph Drawing. He has been a member of the French literary group Oulipo since 1992. He married the French author and illustrator Agnès Rosenstiehl Agnès Rosenstiehl (born December 4, 1941) ...

Italy
Italy ( it, Italia ), officially the Italian Republic, ) or the Republic of Italy, is a country in Southern Europe. It is located in the middle of the Mediterranean Sea, and its territory largely coincides with the homonymous geographical region. Italy is also considered part of Western Europe, and shares land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates of Vatican City and San Marino. It has a territorial exclave in Switzerland, Campione. Italy covers an area of , with a population of over 60 million. It is the third-most populous member state of the European Union, the sixth-most populous country in Europe, and the tenth-largest country in the continent by land area. Italy's capital and largest city is Rome. Italy was the native place of many civilizations such as the Italic peoples and the Etruscans, while due to its central geographic location in Southern Europe and the Mediterranean, the country has also historically been home ...

Researchers In Geometric Algorithms
Research is " creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

21st-century French Mathematicians
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius ( AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emper ...

Oulipo Members
Oulipo (, short for french: Ouvroir de littérature potentielle; roughly translated: ''"workshop of potential literature"'', stylized ''OuLiPo'') is a loose gathering of (mainly) French-speaking writers and mathematicians who seek to create works using constrained writing techniques. It was founded in 1960 by Raymond Queneau and François Le Lionnais. Other notable members have included novelists Georges Perec and Italo Calvino, poets Oskar Pastior and Jean Lescure, and poet/mathematician Jacques Roubaud. The group defines the term ''littérature potentielle'' as (rough translation): "the seeking of new structures and patterns which may be used by writers in any way they enjoy". Queneau described Oulipians as "rats who construct the labyrinth from which they plan to escape." Constraints are used as a means of triggering ideas and inspiration, most notably Perec's "story-making machine", which he used in the construction of '' Life: A User's Manual''. As well as established techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agnès Rosenstiehl
Agnès Rosenstiehl (born December 4, 1941) is a French author and illustrator from Paris. Born from a family of artists, she studied music at the National Conservatory of Music and Dance in Paris and obtained the first harmony prize in 1966 under the name of Agnès Gay. She is best known for a series of children's books following the life of Mimi-Cracra better known to the English language as 'Silly Lilly', and her book "Paris-Pékin par le Transsibérien", which she illustrated and co-wrote with her husband, Pierre Rosenstiehl after an inspirational family trip. Career As a mother, she began creating books for children and collaborated with many publishing houses, from the most famous to the smallest and most emerging. She says she is fascinated by Egyptian antiquity, which leads her to draw her characters always in profile, to use solid colors, to embed writing and drawing. She shows a sustained interest in the French language, subject that she explores in many books, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
