Dorothy Maharam
Dorothy Maharam Stone (July 1, 1917 – September 27, 2014) was an American mathematician born in Parkersburg, West Virginia, who made important contributions to measure theory and became the namesake of Maharam's theorem and Maharam algebra. Life Maharam earned her B.S. degree at Carnegie Institute of Technology in 1937 and her Ph.D. in 1940 under Anna Johnson Pell Wheeler from Bryn Mawr College with a dissertation entitled ''On measure in abstract sets''. Part of her thesis was published in the Transactions of the American Mathematical Society. Then she went on to a postdoc at the Institute for Advanced Study in Princeton, New Jersey, where she first met fellow mathematician Arthur Harold Stone. They married in April 1942. Stone and Maharam both lectured at various universities in the US and the United Kingdom and were faculty at the University of Rochester for many years. She was an invited speaker at a measure theory conference at Northern Illinois University in 1980. Their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parkersburg, West Virginia
Parkersburg is a city in and the county seat of Wood County, West Virginia, Wood County, West Virginia. Located at the confluence of the Ohio River, Ohio and Little Kanawha River, Little Kanawha rivers, it is the state's fourth-largest city and the largest city in the Parkersburg-Marietta-Vienna metropolitan area. The population was 29,749 at the 2020 United States census, 2020 census. The city is about south of Marietta, Ohio. The Baltimore and Ohio Railroad reached Parkersburg in 1857, but lacked a crossing over the Ohio River until after the American Civil War. When the B&O completed the Parkersburg Bridge (CSX) 1868–1870 to Belpre, Ohio, Belpre, it was the longest railroad bridge in the world. The Bureau of the Public Debt, an agency of the U.S. Treasury Department, was relocated from the Washington, D.C. metropolitan area in the late 20th century and headquartered in Parkersburg. In October 2012, it was merged with the Financial Management Service to form the Bureau of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finitely Additive
In mathematics, an additive set function is a function mapping sets to numbers, with the property that its value on a union of two disjoint sets equals the sum of its values on these sets, namely, \mu(A \cup B) = \mu(A) + \mu(B). If this additivity property holds for any two sets, then it also holds for any finite number of sets, namely, the function value on the union of ''k'' disjoint sets (where ''k'' is a finite number) equals the sum of its values on the sets. Therefore, an additive set function is also called a finitely-additive set function (the terms are equivalent). However, a finitely-additive set function might not have the additivity property for a union of an ''infinite'' number of sets. A σ-additive set function is a function that has the additivity property even for countably infinite many sets, that is, \mu\left(\bigcup_^\infty A_n\right) = \sum_^\infty \mu(A_n). Additivity and sigma-additivity are particularly important properties of measures. They are abstrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institute For Advanced Study People
An institute is an organisational body created for a certain purpose. They are often research organisations (research institute, research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of academic department, departments or an autonomous educational institution without a traditional university status such as a "university institute" (see Institute of Technology). In some countries, such as South Korea and India, private schools are sometimes referred to as institutes, and in Spain, secondary schools are referred to as institutes. Historically, in some countries institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from a Latin word ''institutum'' meaning "facility" or "habit"; from ''instituere'' meaning "bui ...

21st-century Women 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 emperor, ...
