Rodica Simion
Rodica Eugenia Simion (January 18, 1955 – January 7, 2000) was a Romanian-American mathematician. She was the Columbian School Professor of Mathematics at George Washington University. Her research concerned combinatorics: she was a pioneer in the study of permutation patterns, and an expert on noncrossing partitions. Biography Simion was one of the top competitors in the Romanian national mathematical olympiads. She graduated from the University of Bucharest in 1974, and immigrated to the United States in 1976.. She did her graduate studies at the University of Pennsylvania, earning a Ph.D. in 1981 under the supervision of Herbert Wilf. After teaching at Southern Illinois University and Bryn Mawr College, she moved to George Washington University in 1987, and became Columbian School Professor in 1997. Recognition She is included in a deck of playing cards featuring notable women mathematicians published by the Association of Women in Mathematics. Research contribution ...

Romanian-American
Romanian Americans are Americans who have Romanian ancestry. According to the 2017 American Community Survey, 478,278 Americans indicated Romanian as their first or second ancestry, however other sources provide higher estimates, which are most likely more accurate, for the numbers of Romanian Americans in the contemporary US; for example, the Romanian-American Network supplies a rough estimate of 1.2 million who are fully or partially of Romanian ethnicity. There is also a significant number of people of Romanian Jewish ancestry, estimated at about 225,000. History The first Romanian known to have been to what is now the United States was Samuel Damian (also spelled Domien), a former priest. Samuel Damian's name appears as far back as 1748, when he placed an advertisement in the '' South Carolina Gazette'' announcing the electrical demonstrations he planned to give and inviting the public to attend. Letters written in 1753 and 1755 by Benjamin Franklin attest to the fact th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Bucharest Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde ...

Cyclohedron
In geometry, the cyclohedron is a d-dimensional polytope where d can be any non-negative integer. It was first introduced as a combinatorial object by Raoul Bott and Clifford Taubes and, for this reason, it is also sometimes called the Bott–Taubes polytope. It was later constructed as a polytope by Martin Markl and by Rodica Simion. Rodica Simion describes this polytope as an associahedron of type B. The cyclohedron is useful in studying knot invariants. Construction Cyclohedra belong to several larger families of polytopes, each providing a general construction. For instance, the cyclohedron belongs to the generalized associahedra that arise from cluster algebra, and to the graph-associahedra, a family of polytopes each corresponding to a Graph (discrete mathematics), graph. In the latter family, the graph corresponding to the d-dimensional cyclohedron is a cycle on d+1 vertices. In topological terms, the Configuration space (mathematics), configuration space of d+1 distinct p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
