DESCRIPTION:The Harder-Narasimhan type of a quiver representation is a dis
 crete invariant parameterised by a real-valued function (called a central 
 charge) defined on the vertices of the quiver. We investigate the strength
  and limitations of Harder-Narasimhan types for several families of quiver
  representations which arise in the study of persistence modules. In parti
 cular\, we introduce the skyscraper invariant\, which amalgamates the HN t
 ypes along central charges supported at single vertices\, and generalise t
 he&nbsp\;rank invariant and generalised&nbsp\;rank invariant studied for m
 ultiparameter persistence modules to arbitrary quiver representations.&nbs
