TITLE: Hodge-Tate decomposition for formal groups
QUESTION [5 upvotes]: Hi All,
Where can I find a proof of the Hodge-Tate decomposition for Lubin-Tate formal
groups?
Thanks!

REPLY [7 votes]: Dear jjj, 
I recommend reading Tate's original paper, which proves the Hodge--Tate decomposition
for all $p$-divisible groups.  If you are nervous about $p$-divisible groups, rather
than formal groups, it would not be difficult to restrict to just this case while
reading the paper.  (And the paper includes an entire section devoted to relating
formal groups to the $p$-divisible groups picture, which is valuable in its own right.)
