Fiber criterion for flatness
WebSo the discriminant can be viewed as a numerical criterion for detecting (non-)smoothness. All of the data needed to determine smoothness is contained in the discriminant. Does there exist a similar one-step gadget for detecting (non-)flatness? (I say "one-step" to mean that the vanishing of infinitely many Tor groups is not an adequate solution. WebOct 15, 2024 · We designed a tellurite microstructure fiber (TMF) and proposed a broadband optical frequency comb generation scheme that was based on electro-optical modulation and cascaded sign-alternated dispersion TMF (CSAD-TMF). In addition, the influence of different nonlinear effects, the ultrashort pulse evolution in the CSAD-TMF …

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. np auto trading orlando floridaWebThe invention provides a carbon fiber plate flatness correction method for a top panel of a laptop.
