Given a sequence of functions bounded in L 1 0 1 , is it possible to extract a subsequence that is pointwise bounded almost everywhere? The main objective of this note is to present an example showing that this is not possible in general. We will also prove a pair of positive results. We show that i
Let β r K be a non-degenerate projective curve of degree r + 2, where r β₯ 3. By means of the Hartshorne-Rao module of we distinguish 4 different possible cases (and an exceptional case which only appears if r = 3). In any case is obtained either by means of an embedding of an arbitrary smooth curve
