Algebraic topology

Algebraic topology is a branch of mathematics that uses tools from abstract algebra to study topological spaces.

See Jacques Feldbau and Algebraic topology

Alsace (Low Alemannic German/Alsatian: Elsàss ˈɛlsɑs; German: Elsass (German spelling before 1996: Elsaß.) ˈɛlzas ⓘ; Latin: Alsatia) is a cultural region and a territorial collectivity in eastern France, on the west bank of the upper Rhine next to Germany and Switzerland.

See Jacques Feldbau and Alsace

Alsace–Lorraine

Alsace–Lorraine (German: Elsaß–Lothringen), officially the Imperial Territory of Alsace–Lorraine (Reichsland Elsaß–Lothringen), was a former territory of the German Empire, located in modern day France.

See Jacques Feldbau and Alsace–Lorraine

André Weil

André Weil (6 May 1906 – 6 August 1998) was a French mathematician, known for his foundational work in number theory and algebraic geometry. Jacques Feldbau and André Weil are 20th-century French mathematicians.

See Jacques Feldbau and André Weil

Associated bundle

In mathematics, the theory of fiber bundles with a structure group G (a topological group) allows an operation of creating an associated bundle, in which the typical fiber of a bundle changes from F_1 to F_2, which are both topological spaces with a group action of G. For a fiber bundle F with structure group G, the transition functions of the fiber (i.e., the cocycle) in an overlap of two coordinate systems Uα and Uβ are given as a G-valued function gαβ on Uα∩Uβ.

See Jacques Feldbau and Associated bundle

Auschwitz concentration camp

Auschwitz concentration camp (also KL Auschwitz or KZ Auschwitz) was a complex of over 40 concentration and extermination camps operated by Nazi Germany in occupied Poland (in a portion annexed into Germany in 1939) during World War II and the Holocaust.

See Jacques Feldbau and Auschwitz concentration camp

Bavaria

Bavaria, officially the Free State of Bavaria, is a state in the southeast of Germany.

See Jacques Feldbau and Bavaria

Charles Ehresmann

Charles Ehresmann (19 April 1905 – 22 September 1979) was a German-born French mathematician who worked in differential topology and category theory. Jacques Feldbau and Charles Ehresmann are 20th-century French mathematicians, Alsatian-German people and category theorists.

See Jacques Feldbau and Charles Ehresmann

Differential geometry

Differential geometry is a mathematical discipline that studies the geometry of smooth shapes and smooth spaces, otherwise known as smooth manifolds.

See Jacques Feldbau and Differential geometry

Drancy internment camp

Drancy internment camp was an assembly and detention camp for confining Jews who were later deported to the extermination camps during the German occupation of France during World War II.

See Jacques Feldbau and Drancy internment camp

Exact sequence

An exact sequence is a sequence of morphisms between objects (for example, groups, rings, modules, and, more generally, objects of an abelian category) such that the image of one morphism equals the kernel of the next.

See Jacques Feldbau and Exact sequence

Fatigue

Fatigue describes a state of tiredness (which is not sleepiness), exhaustion or loss of energy.

See Jacques Feldbau and Fatigue

Fiber bundle

In mathematics, and particularly topology, a fiber bundle (''Commonwealth English'': fibre bundle) is a space that is a product space, but may have a different topological structure.

See Jacques Feldbau and Fiber bundle

Fibration

The notion of a fibration generalizes the notion of a fiber bundle and plays an important role in algebraic topology, a branch of mathematics.

See Jacques Feldbau and Fibration

Flossenbürg concentration camp

Flossenbürg was a Nazi concentration camp built in May 1938 by the SS Main Economic and Administrative Office.

See Jacques Feldbau and Flossenbürg concentration camp

German Empire

The German Empire, also referred to as Imperial Germany, the Second Reich or simply Germany, was the period of the German Reich from the unification of Germany in 1871 until the November Revolution in 1918, when the German Reich changed its form of government from a monarchy to a republic.

See Jacques Feldbau and German Empire

Gestapo

The Geheime Staatspolizei, abbreviated Gestapo, was the official secret police of Nazi Germany and in German-occupied Europe.

See Jacques Feldbau and Gestapo

Homotopy

In topology, a branch of mathematics, two continuous functions from one topological space to another are called homotopic (from ὁμός "same, similar" and τόπος "place") if one can be "continuously deformed" into the other, such a deformation being called a homotopy between the two functions.

See Jacques Feldbau and Homotopy

Homotopy group

In mathematics, homotopy groups are used in algebraic topology to classify topological spaces.

See Jacques Feldbau and Homotopy group

J. H. C. Whitehead

John Henry Constantine Whitehead FRS (11 November 1904 – 8 May 1960), known as "Henry", was a British mathematician and was one of the founders of homotopy theory.

See Jacques Feldbau and J. H. C. Whitehead

Jews

The Jews (יְהוּדִים) or Jewish people are an ethnoreligious group and nation originating from the Israelites of the ancient Near East, and whose traditional religion is Judaism.

See Jacques Feldbau and Jews

Lycée Kléber

The Lycée Kléber is a French public secondary school located in the Alsatian capital Strasbourg.

See Jacques Feldbau and Lycée Kléber

Schutzstaffel

The Schutzstaffel (SS; also stylised as ᛋᛋ with Armanen runes) was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II.

See Jacques Feldbau and Schutzstaffel

Seifert fiber space

A Seifert fiber space is a 3-manifold together with a decomposition as a disjoint union of circles.

See Jacques Feldbau and Seifert fiber space

Sequence

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

See Jacques Feldbau and Sequence

Simplex

In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions.

See Jacques Feldbau and Simplex

Sphere

A sphere (from Greek) is a geometrical object that is a three-dimensional analogue to a two-dimensional circle.

See Jacques Feldbau and Sphere

Thesis

A thesis (theses), or dissertation (abbreviated diss.), is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.

See Jacques Feldbau and Thesis

Topology

Topology (from the Greek words, and) is the branch of mathematics concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself.

See Jacques Feldbau and Topology

University of Strasbourg

The University of Strasbourg (Université de Strasbourg, Unistra) is a public research university located in Strasbourg, France, with over 52,000 students and 3,300 researchers.
