DESCRIPTION:Title: <a href="https://researchseminars.org/talk/notts_ag/46/
 ">Fujita decomposition and Massey product for fibered varieties</a>\nby Fr
 ancesco Zucconi (Udine) as part of Online Nottingham algebraic geometry se
 minar\n\n\nAbstract\nLet $f\\colon X \\to B$ be a semistable fibration whe
 re $X$ is a smooth variety of dimension $n ≥ 2$ and $B$ is a smooth curv
 e. We give an interpretation of the second Fujita decomposition of $f_∗\
 \omega_{X/B}$ in terms of local systems of the relative 1-forms and of the
  relative top forms. We show the existence of higher irrational pencils un
 der natural hypothesis on local subsystems.\n
