Alexander Grothendieck Mathematician

Alexander Grothendieck was a mathematician who became the leading figure in the creation of modern algebraic geometry. His research extended the scope of the field and added elements of commutative algebra, homological algebra, sheaf theory and category theory to its foundations, while his so-called "relative" perspective led to revolutionary advances in many areas of pure mathematics. He is considered by many to be the greatest mathematician of the 20th century.

<i>Dragonflight</i> Novel by Anne McCaffrey

Dragonflight is a science fiction novel by the American-Irish author Anne McCaffrey. It is the first book in the Dragonriders of Pern series. Dragonflight was first published by Ballantine Books in July 1968. It is a fix-up of novellas, including two which made McCaffrey the first woman writer to win a Hugo and Nebula Award.

Emmy Noether German mathematician

Amalie Emmy Noether was a German mathematician who made important contributions to abstract algebra and theoretical physics. She invariably used the name "Emmy Noether" in her life and publications. She was described by Pavel Alexandrov, Albert Einstein, Jean Dieudonné, Hermann Weyl and Norbert Wiener as the most important woman in the history of mathematics. As one of the leading mathematicians of her time, she developed the theories of rings, fields, and algebras. In physics, Noether's theorem explains the connection between symmetry and conservation laws.

Oscar Zariski American mathematician

Oscar Zariski was a Russian-born American mathematician and one of the most influential algebraic geometers of the 20th century.

Georg Alexander Pick Austrian mathematician

Georg Alexander Pick was an Austrian born mathematician. He was born in a Jewish family to Josefa Schleisinger and Adolf Josef Pick. He died in the Theresienstadt concentration camp. Today he is best known for Pick's theorem for determining the area of lattice polygons. He published it in an article in 1899; it was popularized when Hugo Dyonizy Steinhaus included it in the 1969 edition of Mathematical Snapshots.

Algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.

Weyr canonical form

In mathematics, in linear algebra, a Weyr canonical form is a square matrix satisfying certain conditions. A square matrix is said to be in the Weyr canonical form if the matrix satisfies the conditions defining the Weyr canonical form. The Weyr form was discovered by the Czech mathematician Eduard Weyr in 1885. The Weyr form did not become popular among mathematicians and it was overshadowed by the closely related, but distinct, canonical form known by the name Jordan canonical form. The Weyr form has been rediscovered several times since Weyr’s original discovery in 1885. This form has been variously called as modified Jordan form,reordered Jordan form,second Jordan form, and H-form. The current terminology is credited to Shapiro who introduced it in a paper published in the American Mathematical Monthly in 1999.

Eduard Weyr Czech mathematician and university educator

Eduard Weyr was a Czech mathematician now chiefly remembered as the discoverer of a certain canonical form for square matrices over algebraically closed fields. Weyr presented this form briefly in a paper published in 1885. He followed it up with a more elaborate treatment in a paper published in 1890. This particular canonical form has been named as the Weyr canonical form in a paper by Shapiro published in The American Mathematical Monthly in 1999. Previously, this form has been variously called as modified Jordan form, reordered Jordan form, second Jordan form, and H-form.
