Type Decomposition in Posets
Motivated by the classical type decomposition of von Neumann algebras, and
various more recent extensions to other structures, we develop a type
decomposition theory for general posets
Ringel's conjecture for domestic string algebras
We classify indecomposable pure injective modules over domestic string
algebras, verifying Ringel's conjecture on the structure of such modules.Comment: minor correction
