Weba smooth manifold structure, so the canonical projection p : M → MR is a smooth fibration. We show that under the additional assumption that R is a complete vector ... hypersurface of contact type spans its characteristic distribution. It is proved in [21] that any hypersurface of contact type can be obtained by a symplectic-to-contact ... http://www-personal.umich.edu/~mmustata/lecture2_rationality.pdf

Weba weakly concave domain with smooth boundary. In this paper, we prove the following Hartogs-Bochner type theorem: Theorem 1 Let M be a connected C2 hypersurface of P n(C) (n ≥ 2) which divides Pn(C) in two connected open sets Ω1 and Ω2. Then there exists i ∈ {1,2} such that for any C1 CR function f : M → C, there exists a Web27 Oct 2024 · Let f : B → R be a d + 1 times continuously differentiable function on the unit ball B, with max z∈Bn‖f(z)‖ = 1. A well-known fact is that if f vanishes on a set Z ⊂ B with a … len do thresh sp

WebAs an example, we improve upon a theorem by Coray on smooth cubic surfaces X ⊂P3 k, in the case when X is diagonal-full, by showing that if X(K) 6=∅for some ... k is a degree 2 hypersurface, then X(L) 6= ∅for some extension L/kof odd degree implies that X(k) 6=∅. A natural question to ask is whether Springer’s theorem Web14 Oct 2024 · A hypersurface is said to be biharmonic if its defining isometric immersion is a biharmonic map, that is, a smooth map which is a critical point of the so-called bienergy … WebIn the following article : "H.
