Anna Pell Wheeler
Anna Johnson Pell Wheeler (née Johnson; May 5, 1883 – March 26, 1966) was an American mathematician. She is best known for early work on linear algebra in infinite dimensions, which has later become a part of functional analysis.Louise S. Grinstein and Paul J. Campbell, "Anna Anna Johnson Pell Wheeler: Her life and work, Historia Mathematica 9(1982)37–53 Biography Anna Johnson was born on May 5, 1883, to Swedish immigrant parents in Calliope, Iowa in the United States. Her father, Andrew Gustav Johnson, was a furniture dealer and undertaker. Her mother, Amelia (née Friberg), was a homemaker. Both of Johnson's parents came from the parish of Lyrestad, in Västergötland, Sweden. Johnson had two older siblings, Esther and Elmer. At the age of nine her family moved to Akron, Iowa and she was enrolled in a private school.

Calliope, Iowa
Calliope, Iowa was an incorporated town in northwestern Iowa. Calliope was formally incorporated in 1882. It served as the county seat of Sioux County, Iowa.

However, the citizens of a Dutch settlement of Orange City, Iowa Orange City is a city in, and the county seat of, Sioux County, Iowa, United States. Its population was 6,267 in the 2020 census, an increase from 5,582 in 2000. Named after William of Orange, the community maintains its Dutch settler tradition ... believed that the county seat should be moved to their city. On January 22, 1872, fifty-five men from Orange City used horses and sleighs to conduct a raid on Calliope. They brought the county books, the safe containing the county money, and the county seal back with them to Orange City.

Marion Cameron Gray
Marion Gray (26 March 1902 – 16 September 1979) was a Scottish mathematician who discovered a graph with 54 vertices and 81 edges while working at American Telephone & Telegraph. The graph is commonly known as the Gray graph. Early life and education Marion Gray was born in Ayr, Scotland on 26 March 1902 to Marion (née Cameron) and James Gray.

Västergötland
Västergötland (), also known as West Gothland or the Latinized version Westrogothia in older literature, is one of the 25 traditional non-administrative provinces of Sweden (''landskap'' in Swedish), situated in the southwest of Sweden. Västergötland is home to Gothenburg, the second largest city in Sweden, which is situated along a short stretch of the Kattegat strait. The province is bordered by Bohuslän, Dalsland, Värmland, Närke, Östergötland, Småland and Halland, as well as the two largest Swedish lakes Vänern and Vättern. Victoria, Crown Princess of Sweden is Duchess of Västergötland. Administration The provinces of Sweden serve no administrative function. Instead, that function is served by counties of Sweden. From the 17th century up until 31 December 1997, Västergötland was divided into Skaraborg County, Älvsborg County and a minor part of Gothenburg and Bohus County. From 1 January 1998 nearly all of the province is in the newly created Västra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swedish People
Swedes ( sv, svenskar) are a North Germanic ethnic group native to the Nordic region, primarily their nation state of Sweden, who share a common ancestry, culture, history and language. They mostly inhabit Sweden and the other Nordic countries, in particular Finland where they are an officially recognized minority, with a substantial diaspora in other countries, especially the United States. Etymology The English term "Swede" has been attested in English since the late 16th century and is of Middle Dutch or Middle Low German origin. In Swedish, the term is ''svensk'', which is from the name of '' svear'' (or Swedes), the people who inhabited Svealand in eastern central Sweden, and were listed as ''Suiones'' in Tacitus' history '' Germania'' from the first century AD. The term is believed to have been derived from the Proto-Indo-European reflexive pronominal root, , as the Latin ''suus''. The word must have meant "one's own (tribesmen)". The same root and original meaning i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Analysis
Functional analysis is a branch of mathematical analysis, the core of which is formed by the study of vector spaces endowed with some kind of limit-related structure (e.g. Inner product space#Definition, inner product, Norm (mathematics)#Definition, norm, Topological space#Definition, topology, etc.) and the linear transformation, linear functions defined on these spaces and respecting these structures in a suitable sense. The historical roots of functional analysis lie in the study of function space, spaces of functions and the formulation of properties of transformations of functions such as the Fourier transform as transformations defining continuous function, continuous, unitary operator, unitary etc. operators between function spaces. This point of view turned out to be particularly useful for the study of differential equations, differential and integral equations. The usage of the word ''functional (mathematics), functional'' as a noun goes back to the calculus of variati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Linear Differential Equation
In mathematics, a linear differential equation is a differential equation that is defined by a linear polynomial in the unknown function and its derivatives, that is an equation of the form :a_0(x)y + a_1(x)y' + a_2(x)y'' \cdots + a_n(x)y^ = b(x) where and are arbitrary differentiable functions that do not need to be linear, and are the successive derivatives of an unknown function of the variable . Such an equation is an ordinary differential equation (ODE). A ''linear differential equation'' may also be a linear partial differential equation (PDE), if the unknown function depends on several variables, and the derivatives that appear in the equation are partial derivatives. A linear differential equation or a system of linear equations such that the associated homogeneous equations have constant coefficients may be solved by quadrature, which means that the solutions may be expressed in terms of integrals. This is also true for a linear equation of order one, with non-con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
