Abstract
Let 𝐶 ⊂ 𝐏𝑛 be a smooth projectively normal curve. Let 𝑍 be the scheme-theoretic base locus of 𝐻0(𝐏𝑛, 𝐼𝐶(2)) and 𝑍′ the connected component of 𝑍 containing 𝐶. Here we show that 𝑍′ = 𝐶 in certain cases (e.g., non-special line bundles with degree near to 2𝑝𝑎(𝐶)–2 or certain special line bundles on general 𝑘-gonal curves).
Key words and phrases:: Quadric hypersurfaces; 𝑘-gonal curves; gonality; projective normality; normally generated line bundle
