All proposed directions have been adressed 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 stuides, some just strated). Very balanced research 
team. Objectives 1,3, and 4 gain more progress than the other. 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 imporession is 
EXTREMELY POSITIVE. Very sucessfull project so far.
