the usual castelnuovo s argument and special subhomaloidal
... Actually, the above assumptions on X imply that it satis�es property N p of Green for p = 2(r − n) + 1 − d , which in turn implies the quoted consequences (see [1], proposition 2). Here we have given a direct geometric proof, based on Castelnuovos idea that a set of 2s + 1 points in general linear ...

... Note. In senior level analysis, it is shown that an open set of real numbers consist of a countable number of maximal connected components which are themselves open intervals. See Theorem 3-5 of http://faculty.etsu.edu/gardnerr/4217/notes/ Supplement-Open-Sets.pdf. In this section, we consider more ...

HOMOTOPY THEORY 1. Homotopy Let X and Y be two topological
... It is easily seen that homotopy is an equivalence relation. The fundamental problem of algebraic topology is to calculate [X, Y ], the set of homotopy classes of maps from X to Y , for given spaces X and Y . 1.2. Definition. The map f : X → Y is a homotopy equivalence if there exists a map g : Y → X ...

... hence it is irreducible. Example 2.1.7. An is irreducible, since it correspondence to the Zero ideal in A, which is prime. An = Z(0), since we know that 0 is a prime ideal, then Z(0) is irreducible. Example 2.1.8. Let f be an irreducible polynomial in A = K[x, y]. Then f generates a prime ideal in A ...

... such that the tangent space at each point q ∈ Q is the corresponding Hq ⊂ T Nq . The condition that τ = 0 is the same as saying that the sections Γ(H) are closed under Lie bracket. There is a dual formulation in terms of differential forms: if ψ is a form on N which vanishes when restricted to H the ...
