Finally, in Section 9 we pose open problems, formulate conjectures and exhibit a relation between hypergraph LSS-ideals and coordinate … WebSo the class of a hyperplane corresponds to all global sections of $\mathcal O(1)$, and hence we can identify these two sets (for our purposes). And since $\mathcal O(1)$ is generated by global sections, they determine $\mathcal (X)$.-Here's an example of what is ment by "generated by a hyperplane section".
In mathematics, specifically in algebraic geometry and algebraic topology, the Lefschetz hyperplane theorem is a precise statement of certain relations between the shape of an algebraic variety and the shape of its subvarieties. More precisely, the theorem says that for a variety X embedded in projective space and a hyperplane section Y, the homology, cohomology, and homotopy groups of X determine those of Y. A result of this kind was first stated by Solomon Lefschetz for homology gr…

Let X be an n-dimensional complex projective algebraic variety in CP N, and let Y be a hyperplane section of X such that U = X ∖ Y is smooth.

If f is a closed immersion, for example, it follows that the pullback f ∗ O ( 1 ) {\displaystyle f^{*}O(1)} is the line bundle on X associated to a hyperplane section (the intersection of X with a hyperplane in P n … standard form 182 trainingIn geometry, a hyperplane is a subspace whose dimension is one less than that of its ambient space. For example, if a space is 3-dimensional then its hyperplanes are the 2-dimensional planes, while if the space is 2-dimensional, its hyperplanes are the 1-dimensional lines. This notion can be used in any general … Meer weergeven In geometry, a hyperplane of an n-dimensional space V is a subspace of dimension n − 1, or equivalently, of codimension 1 in V.
