4Chern-Klasse — In der Mathematik, genauer in der algebraischen Topologie und in der Differentialgeometrie und topologie, ist eine Chernklasse ein spezieller Typ einer charakteristischen Klasse, die komplexen Vektorbündeln zugeordnet wird. Chernklassen sind nach …
5Logarithmic derivative — In mathematics, specifically in calculus and complex analysis, the logarithmic derivative of a function f is defined by the formula where f ′ is the derivative of f. When f is a function f(x) of a real variable x, and takes real, strictly… …
6Étale cohomology — In mathematics, the étale cohomology groups of an algebraic variety or scheme are algebraic analogues of the usual cohomology groups with finite coefficients of a topological space, introduced by Grothendieck in order to prove the Weil… …
