Paul Celan (/ ˈ s ɛ l æ n /; [1] German: [ˈtseːlaːn]), born Paul Antschel, (23 November 1920 – c. 20 April 1970) was a Romanian-born French poet, Holocaust survivor, and literary translator. Celan is regarded as one of the most important figures in German-language literature of the post- World War II era and a poet whose verse has ...
A constant function of a single variable, such as () =, has a graph of a horizontal line parallel to the x-axis. [7] Such a function always takes the same value (in this case 5), because the variable does not appear in the expression defining the function. Graph of () =.
Atemwende, (translated into English as Breathturn), is a 1967 German-language poetry collection by Paul Celan. It was originally published in English by Sun & Moon Press in 1995, then republished in 2006 when Sun & Moon Press became Green Integer. [1] [2]
The definitions are applied to graphs as follows. If a function (a -cochain) is defined at the nodes of a graph: ,,, … then its exterior derivative (or the differential) is the difference, i.e., the following function defined on the edges of the graph (-cochain):
The image of a function f(x 1, x 2, …, x n) is the set of all values of f when the n-tuple (x 1, x 2, …, x n) runs in the whole domain of f.For a continuous (see below for a definition) real-valued function which has a connected domain, the image is either an interval or a single value.
set-valued function with a closed graph. If F : X → 2 Y is a set-valued function between topological spaces X and Y then the following are equivalent: F has a closed graph (in X × Y); (definition) the graph of F is a closed subset of X × Y; and if Y is compact and Hausdorff then we may add to this list:
The federal government has been quietly sitting on a heap of documents about dangerous gain-of-function biological research — and Sen. Rand Paul says it’s failing to cough them up, despite ...
For z = 1/3, the inverse of the function x = 2 C 1/3 (y) is the Cantor function. That is, y = y(x) is the Cantor function. In general, for any z < 1/2, C z (y) looks like the Cantor function turned on its side, with the width of the steps getting wider as z approaches zero.
