All proposed directions have been addressed with significant results obtained. Many achievements are based on the additive structure of indecomposables developed earlier by PI. Several PostDocs participated in different projects, as well as PhD students (some accomplished their studies, some just started). Very balanced research team. Objectives 1, 3, and 4 gain more progress than the others. Probably the main result here is the solution of the weak lifting problem and proof of the weak Kitaoka's conjecture by Kala and Yatsyna (already published in Bull London Math Soc). The work should continue as it is developing in a good way. My general impression is EXTREMELY POSITIVE. Very successful project so far.
