✦ Synopsis
This paper continues the study of the functor, introduced in 7 . Let A s k Q Q be a connected wild hereditary path-algebra, where Q Q is some finite quiver without oriented cycles and k is some field. The category of finitely generated left A-modules is denoted by A-mod, and maps are written opposite to the scalars. Assume A has at least three simple modules and let X be a quasi-simple regular module without self-extensions. The right perpendicular category X H of X is the full subcategory of
structed. For the construction of this functor tilting theory was used.
