WebSkeletal muscle is under both voluntary and involuntary control. Smooth muscle is under both voluntary and involuntary control. Cardiac muscle is under both voluntary and involuntary control. Skeletal and cardiac muscle are under voluntary control while smooth muscle is under involuntary control. 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 …
WebMar 18, 2014 · 1 To be a little more exact, one of the commonly accepted definitions of a variety is a scheme (whatever that means) over an algebraically closed field that is reduced, plus some other conditions. A scheme is geometrically reduced if, when viewed over an algebraically closed field it is reduced. Hence a variety is always geometrically reduced. WebAug 3, 2024 · The Lagrangian Quot scheme LQ_ {-e} (W) parameterizes subsheaves of rank n and degree -e which are isotropic with respect to the symplectic form. We prove that LQ_ {-e} (W) is irreducible and generically smooth of the expected dimension for all large e, and that a generic element is saturated and stable. 1 Introduction
WebMar 1, 2024 · We use families of curves on cones to show that under certain numerical assumptions for d, g and r, the scheme \ ( {\mathcal {I}}_ {d,g,r}\) acquires generically smooth components whose general... WebThe only place where c h a r = 0 is used is to conclude that the family f: W → G of hyperplane sections of X mapping to G = P G L n is generically smooth. If you know that the general fiber is reduced, then it implies that the general fiber is generically smooth. In order to get Bertini, we need that f is generically smooth on G.
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.

This definition agrees with the topological one above, because for irreducible algebraic varieties any non-empty open set is dense.
