Web1. Since flatness is affine local on the target, we may as well assume that that Y is affine, say Spec ( A), and X = Proj ( S ∙), for S ∙ some graded A -algebra. This then says that S m ∙ is A -flat for sufficiently large m. You need to show that ( ( S ∙) f) 0 is flat for all homogenous f which are not nilpotent. WebSpectral flatness estimates to which degree the frequencies in a spectrum are uniformly distributed (noise-like) [109]. The spectral flatness is the ratio of the geometric and the arithmetic mean of a subband in the power spectrum [103]. The same definition is used by the MPEG-7 standard for the audio spectrum flatness descriptor [65]. Spectral ...
WebThen $C = B/I$ is a finite type $A$-algebra whose generic fiber $(B/I)_ K$ is nonzero (as $h_\eta \not= 0$). We apply generic flatness to $A \to C$ and $A \to B/hB$, see Algebra, … WebOne fringe corresponds to ½ of a wave. 1λ flatness is considered typical grade, λ/4 flatness is considered precision grade, and λ/20 is considered high precision grade.
