Nakayama algebra

In algebra, a Nakayama algebra or generalized uniserial algebra is an algebra such that each left or right indecomposable projective module has a unique composition series. They were studied by who called them "generalized uni-serial rings". These algebras were further studied by and later by , by and by .
An example of a Nakayama algebra is "k"["x"]/("x""n") for "k" a field and "n" a positive integer. 
Current usage of "uniserial" differs slightly: an explanation of the difference appears here.
