French translation for "betti number"

nombre de betti

Example Sentences:

	1.	Joint work with Kentaro Yano (1912–1993) led to the 1953 book Curvature and Betti Numbers. Un travail en collaboration avec Kentaro Yano (1912-1993) aboutit en 1953 sur le livre Curvature and Betti Numbers.
	2.	More generally still, for any topological space, we can define the nth Betti number bn as the rank of the n-th singular homology group. Plus généralement encore, pour un espace topologique quelconque, on définit le n-ième nombre de Betti bn comme le rang (en) du n-ième groupe d'homologie singulière.
	3.	For an orientable surface S the Euler characteristic χ(S) is 2 − 2 g {\displaystyle 2-2g\,} where g is the genus (the number of handles), since the Betti numbers are 1, 2g, 1, 0, 0, ... . Pour une surface orientable S, la caractéristique d'Euler χ ( S )
	4.	The Euler characteristic can then be defined as the alternating sum χ = b 0 − b 1 + b 2 − b 3 + ⋯ . {\displaystyle \chi =b_{0}-b_{1}+b_{2}-b_{3}+\cdots .} This quantity is well-defined if the Betti numbers are all finite and if they are zero beyond a certain index n0. La caractéristique d'Euler peut alors être définie comme la somme alternée χ = b 0 − b 1 + b 2 − b 3 + ⋯
