Irene A. Glinosn intersections always contain a certain number of special cases due to parallel lines or asymptotes. For example, in the plane two distinct lines meet at a unique point except when they are parallel. In projective space, there are no such exceptions.去掉 发表于 2025-3-25 21:25:13
Mark Dusheiko(curves) and 2 (surfaces)… We will give a very natural topological definition of dimension, which is not always easy to work with, followed by other definitions which are easier to work with but which depend on results from algebra.容易懂得 发表于 2025-3-26 00:28:09
Silvia Balia,Rinaldo Brau,Emanuela MarrocuWe consider a general member of a Lefschetz pencil of surfaces in weighted projective 3-spaces of type (1,1,a,b) where gad(a,b)=1. We show that such a surface either has Picard number equal to 1 or all of its 2-cohomolgy is algebraic.PALL 发表于 2025-3-26 07:54:18
