William Edward Story
William Edward Story (April 29, 1850 – April 10, 1930) was an American mathematician who taught at Johns Hopkins University and Clark University. William was born in Boston to Isaac Marion Story (1818-1901) and Elizabeth Bowen Woodberry (1817-1888). He attended high school in Somerville, Massachusetts, and entered Harvard University in the fall of 1867. He graduated with honors in mathematics and began graduate study in Germany in September 1871. In Berlin he attended lectures of Weierstrass, Ernst Kummer, Helmholtz and Dove. In Leipzig he heard Karl Neumann, Bruhns, Mayer, Van der Müll, and Engelmann. He earned a Ph.D. in Leipzig in 1875 with a dissertation "On the algebraic relations existing between the polars of a binary quantic." W.E. Story began his teaching career at Harvard as a tutor. With the establishment of Johns Hopkins University in 1876, Story was recruited by Daniel Coit Gilman as an Associate. J. J. Sylvester led the program in mathematics. Until 1879, St ...

Karl Neumann (mathematician)
Carl Gottfried Neumann (also Karl; 7 May 1832 – 27 March 1925) was a German mathematician. Biography Neumann was born in Königsberg, Prussia, as the son of the mineralogist, physicist and mathematician Franz Ernst Neumann (1798–1895), who was professor of mineralogy and physics at Königsberg University. Carl Neumann studied in Königsberg and Halle and was a professor at the universities of Halle, Basel, Tübingen, and Leipzig. While in Königsberg, he studied physics with his father, and later as a working mathematician, dealt almost exclusively with problems arising from physics. Stimulated by Bernhard Riemann's work on electrodynamics, Neumann developed a theory founded on the finite propagation of electrodynamic actions, which interested Wilhelm Eduard Weber and Rudolf Clausius into striking up a correspondence with him. Weber described Neumann's professorship at Leipzig as for "higher mechanics, which essentially encompasses mathematical physics," and his lectures did ...

Docent
The title of docent is conferred by some European universities to denote a specific academic appointment within a set structure of academic ranks at or below the full professor rank, similar to a British readership, a French " ''maître de conférences''" (MCF), and equal to or above the title of " associate professor". Docent is also used at some (mainly German) universities generically for a person who has the right to teach. The term is derived from the Latin word ''docēns'', which is the present active participle of ''docēre'' (to teach, to lecture). Becoming a docent is often referred to as Habilitation or doctor of science and is an academic qualification that shows that the holder is qualified to be employed at the level of associate or full professor. Docent is the highest academic title in several countries, and the qualifying criteria are research output that corresponds to 3-5 doctoral dissertations, supervision of PhD students, and experience in teaching at the ...

Henry Taber
Henry Taber (1860–1936) was an American mathematician. Biography Taber studied mechanical engineering at Sheffield Scientific School from 1877 to 1882. Then, he went to Baltimore to study mathematics at Johns Hopkins University, under Charles Sanders Peirce and William Edward Story. He was awarded a doctorate in 1888, with a dissertation probably tutored by Story. The following year he was assistant professor at Johns Hopkins, but in 1889, on Clark University's foundation hiring his teacher and friend, Story, he went also to Clark. Both remained at Clark as mathematics professors until retirement in 1921. His brother, Robert Taber, was a well known Broadway theatre actor. Taber promulgated linear algebra as expressed with matrices, in particular the symmetric matrix, skew-symmetric matrix, and orthogonal matrix.

Oskar Bolza
Oskar Bolza (12 May 1857 – 5 July 1942) was a German mathematician, and student of Felix Klein. He was born in Bad Bergzabern, Palatinate, then a district of Bavaria, known for his research in the calculus of variations, particularly influenced by Karl Weierstrass' 1879 lectures on the subject. Life Bolza entered the University of Berlin in 1875. His first interest was in linguistics, then he studied physics with Kirchhoff and Helmholtz, but experimental work did not attract him, so he decided on mathematics in 1878. The years 1878–1881 were spent studying under Elwin Christoffel and Theodor Reye at Strasbourg, Hermann Schwarz at Göttingen, and particularly Karl Weierstrass in Berlin. In the spring of 1888 he landed in Hoboken, NJ, searching for a job in the United States: he succeeded in finding a position in 1889 at Johns Hopkins University and then at the then newly founded Clark University.According to . In 1892 Bolza joined the University of Chicago and worked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invariant Theory
Invariant theory is a branch of abstract algebra dealing with actions of groups on algebraic varieties, such as vector spaces, from the point of view of their effect on functions. Classically, the theory dealt with the question of explicit description of polynomial functions that do not change, or are ''invariant'', under the transformations from a given linear group. For example, if we consider the action of the special linear group ''SLn'' on the space of ''n'' by ''n'' matrices by left multiplication, then the determinant is an invariant of this action because the determinant of ''A X'' equals the determinant of ''X'', when ''A'' is in ''SLn''. Introduction Let G be a group, and V a finite-dimensional vector space over a field k (which in classical invariant theory was usually assumed to be the complex numbers). A representation of G in V is a group homomorphism \pi:G \to GL(V), which induces a group action of G on V. If k /math> is the space of polynomial functions on ...

Elliptic Function
In the mathematical field of complex analysis, elliptic functions are a special kind of meromorphic functions, that satisfy two periodicity conditions. They are named elliptic functions because they come from elliptic integrals. Originally those integrals occurred at the calculation of the arc length of an ellipse. Important elliptic functions are Jacobi elliptic functions and the Weierstrass \wp-function. Further development of this theory led to hyperelliptic functions and modular forms. Definition A meromorphic function is called an elliptic function, if there are two \mathbb- linear independent complex numbers \omega_1,\omega_2\in\mathbb such that : f(z + \omega_1) = f(z) and f(z + \omega_2) = f(z), \quad \forall z\in\mathbb. So elliptic functions have two periods and are therefore also called ''doubly periodic''. Period lattice and fundamental domain Iff is an elliptic function with periods \omega_1,\omega_2 it also holds that : f(z+\gamma)=f(z) for every linear ...

Quaternions
In mathematics, the quaternion number system extends the complex numbers. Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space. Hamilton defined a quaternion as the quotient of two '' directed lines'' in a three-dimensional space, or, equivalently, as the quotient of two vectors. Multiplication of quaternions is noncommutative. Quaternions are generally represented in the form :a + b\ \mathbf i + c\ \mathbf j +d\ \mathbf k where , and are real numbers; and , and are the ''basic quaternions''. Quaternions are used in pure mathematics, but also have practical uses in applied mathematics, particularly for calculations involving three-dimensional rotations, such as in three-dimensional computer graphics, computer vision, and crystallographic texture analysis. They can be used alongside other methods of rotation, such as Euler angles and rotation matrices, or as an alternative to them, d ...

Associate Professor
Associate professor is an academic title with two principal meanings: in the North American system and that of the ''Commonwealth system''. Overview In the ''North American system'', used in the United States and many other countries, it is a position between assistant professor and a full professorship. In this system an associate professorship is typically the first promotion obtained after gaining a faculty position, and in the United States it is usually connected to tenure. In the '' Commonwealth system'' (Canada included), the title associate professor is traditionally used in place of reader in certain countries.UK Academic Job Titles Explained academicpositions.com Like the reader title it ranks above senior lecturer – which corresponds to associ ...
