Generically smooth
WebTo clarify a few things: Sard's theorem states that any surjective smooth (meaning C ∞) map f: X → Y of smooth manifolds is generically a submersion (that is: generically on X as well as on Y ). Now in algebraic geometry the analogue to a submersion in differential topology is called a smooth morphism of relative dimension dim X − dim Y. WebThere are various statements which would fit your criteria. They often times go under the heading of 'generic smoothness'. For example, if char ( k) = 0, and X / k is smooth, then …

WebDec 23, 2024 · We consider the barotropic Euler equations in dimension d>1 with decaying density at spatial infinity. The phase portrait of the nonlinear ode governing the equation for spherically symmetric self-similar solutions has been introduced in the pioneering work of Guderley. It allows to construct global profiles of the self-similar problem, which however …
