Weighted partially orderd sets of finite type
We define representations of weighted posets and construct for them reflection functors. Using this technique we prove that a weighted poset is of finite representation type if and only if its Tits form is weakly positive; then indecomposable representations are in one-to-one correspondence with...

construct for them reflection functors. Using this technique we
prove that a weighted poset is of finite representation type if and
only if its Tits form is weakly positive; then indecomposable representations are in one-to-one correspondence with the positive roots
of the Tits form.
