Exponential functionThe exponential function is a mathematical function denoted by or (where the argument x is written as an exponent). Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras. The exponential function originated from the notion of exponentiation (repeated multiplication), but modern definitions (there are several equivalent characterizations) allow it to be rigorously extended to all real arguments, including irrational numbers.
Exponential growthExponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself. Described as a function, a quantity undergoing exponential growth is an exponential function of time, that is, the variable representing time is the exponent (in contrast to other types of growth, such as quadratic growth).
TetrationIn mathematics, tetration (or hyper-4) is an operation based on iterated, or repeated, exponentiation. There is no standard notation for tetration, though and the left-exponent xb are common. Under the definition as repeated exponentiation, means , where n copies of a are iterated via exponentiation, right-to-left, i.e. the application of exponentiation times. n is called the "height" of the function, while a is called the "base," analogous to exponentiation. It would be read as "the nth tetration of a".
EquinumerosityIn mathematics, two sets or classes A and B are equinumerous if there exists a one-to-one correspondence (or bijection) between them, that is, if there exists a function from A to B such that for every element y of B, there is exactly one element x of A with f(x) = y. Equinumerous sets are said to have the same cardinality (number of elements). The study of cardinality is often called equinumerosity (equalness-of-number). The terms equipollence (equalness-of-strength) and equipotence (equalness-of-power) are sometimes used instead.
Green's relationsIn mathematics, Green's relations are five equivalence relations that characterise the elements of a semigroup in terms of the principal ideals they generate. The relations are named for James Alexander Green, who introduced them in a paper of 1951. John Mackintosh Howie, a prominent semigroup theorist, described this work as "so all-pervading that, on encountering a new semigroup, almost the first question one asks is 'What are the Green relations like?'" (Howie 2002).
Martha Reeves (anchorite)Martha Reeves (born 1941) is a vowed Anglican solitary (or anchorite), with Rowan Williams, the former Archbishop of Canterbury, as bishop-protector. A graduate of the Madeira School (Class of 1959), she is also a Stanford-educated professor of theology who has written numerous articles and books under the name "Maggie Ross" as well as translated a number of Carthusian Novice Conferences. Reeves, at one time Desmond Tutu's spiritual director, was Bell Distinguished Professor in Anglican and Ecumenical Studies appointed to the Department of Philosophy and Religion, Kendall College of Arts and Sciences, The University of Tulsa.
Justin TrudeauJustin Pierre James Trudeau (ˈtruːdoʊ,_truːˈdoʊ , ʒystɛ̃ pjɛʁ dʒɛms tʁydo; born December 25, 1971) is a Canadian politician serving as the 23rd and current prime minister of Canada since 2015 and leader of the Liberal Party since 2013. Trudeau is the second-youngest prime minister in Canadian history after Joe Clark; he is also the first to be the child of a previous holder of the post, as the eldest son of Pierre Trudeau. Trudeau was born in Ottawa and attended Collège Jean-de-Brébeuf.
Political positions of John McCainU.S. Senator John McCain, a Republican Party politician from Arizona who was a member of the U.S. Congress from 1983 until his death in office in 2018, a two-time U.S. presidential candidate, and the nominee of the Republican Party in the 2008 U.S. Presidential election, took positions on many political issues through his public comments, his presidential campaign statements, and his senatorial voting record. Online, McCain used his Senate web site and his 2008 campaign web site to describe his political positions.
NK Lokomotiva ZagrebNogometni klub Lokomotiva Zagreb (Lokomotiva Zagreb Football Club), commonly known as Lokomotiva Zagreb or simply Lokomotiva, is a Croatian professional football club based in Zagreb. It competes in the Croatian First Football League, the country's top division. Founded in 1914, the club's only period of success came in the late 1940s and early 1950s before spending most of the following five decades in lower-level leagues. Between 2007 and 2009 they won three consecutive promotions to rise from the fourth level to the first in the Croatian football league system.
