We use this to give a simpler proof of cd(P 3 − C) = 1 by using Budach’s method for these curves.We investigate the nature of curves on cubic surfaces such that the cubic surface minus these curves is an affine variety. We give combinatorial conditions for the existence of such curves.vii, 28 leavesEnglishinfo:eu-repo/semantics/openAccessCohomological dimensionIntersection TheoryCubic surfacesDel Pezzo surfacesQA612.3 .T87 2004Homology theory.ThesisBILKUTUPB084176
