Richard A. Brualdi
R. A. Brualdi is a professor emeritus of combinatorial mathematics at the University of Wisconsin–Madison. Brualdi received his Ph.D. from Syracuse University in 1964; his advisor was H. J. Ryser. Brualdi is an Editor-in-Chief of the Electronic Journal of Combinatorics. He has over 200 publications in several mathematical journals. According to current on-line database of Mathematics Genealogy Project, Richard Brualdi has 37 Ph.D. students and 48 academic descendants. The concept of incidence coloring was introduced in 1993 by Brualdi and Massey. He received the Euler medal from the Institute of Combinatorics and its Applications in 2000.

Derby, Connecticut
Derby is a city in New Haven County, Connecticut, United States, approximately 8 miles west-northwest of New Haven. It is located in southwest Connecticut at the confluence of the Housatonic and Naugatuck Rivers. It borders the cities of Ansonia to the north and Shelton to the southwest, and the towns of Orange to the south, Seymour to the northwest, and Woodbridge to the east. The population was 12,325 at the 2020 census. It is the smallest city in Connecticut by area, at 5.3 square miles. Derby was settled in 1642 as an Indian trading post under the name Paugasset. It was named after Derby, England, in 1675. It included what are now Ansonia, Seymour, Oxford, and parts of Beacon Falls. Derby is home to the first electric trolley system in New England, only the second in the United States. It is also home to the first electric locomotive in U.S. history to be built and successfully used commercially for hauling freight. The locomotive, built in 1888, is still kept in ru ...

Incidence Coloring
In graph theory, the act of coloring generally implies the assignment of labels to vertices, edges or faces in a graph. The incidence coloring is a special graph labeling where each incidence of an edge with a vertex is assigned a color under certain constraints. Definitions Below ''G'' denotes a simple graph with non-empty vertex set (non-empty) ''V''(''G''), edge set ''E''(''G'') and maximum degree Δ(''G''). Definition. An incidence is defined as a pair (''v'', ''e'') where v\in V(G) is an end point of e\in E(G). In simple words, one says that vertex ''v'' is incident to edge ''e''. Two incidences (''v'', ''e'') and (''u'', ''f'') are said to be adjacent or neighboring if one of the following holds: * ''v'' = ''u'', ''e'' ≠ ''f'' * ''e'' = ''f'', ''v'' ≠ ''u'' * ''e'' = , ''f'' = and ''v'' ≠ ''w''. Definition. Let ''I''(''G'') be the set of all incidences of ''G''. An incidence coloring of ''G'' is a function c: I(G)\to\N that takes distinct values on adjacent ...

University Of Wisconsin–Madison Faculty
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' ...

21st-century American Mathematicians
The 1st century was the century spanning AD 1 (Roman numerals, I) through AD 100 (Roman numerals, 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 History by period, historical period. The 1st century also saw the Christianity in the 1st century, 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 inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Mathematical Society
The American Mathematical Society (AMS) is an association of professional mathematicians dedicated to the interests of mathematical research and scholarship, and serves the national and international community through its publications, meetings, advocacy and other programs. The society is one of the four parts of the Joint Policy Board for Mathematics and a member of the Conference Board of the Mathematical Sciences. History The AMS was founded in 1888 as the New York Mathematical Society, the brainchild of Thomas Fiske, who was impressed by the London Mathematical Society on a visit to England. John Howard Van Amringe was the first president and Fiske became secretary. The society soon decided to publish a journal, but ran into some resistance, due to concerns about competing with the American Journal of Mathematics. The result was the '' Bulletin of the American Mathematical Society'', with Fiske as editor-in-chief. The de facto journal, as intended, was influential ...
