Contribution
It provides new sufficient conditions for the existence of proper costratifying systems and clarifies their connection to previously studied stratifying systems.
Findings
Established new sufficient conditions for proper costratifying systems
Analyzed the relation between proper costratifying systems and Erdmann-Sáenz stratifying systems
Enhanced theoretical framework for algebraic stratification methods
Abstract
In this paper we further study the notion of proper costratifying systems, defined in \cite{MPV}. We give sufficient conditions for their existence, and investigate the relation between the stratifying systems defined by K. Erdmann and C. S\'aenz in \cite{ES} with the proper costratifying systems.
