概要
We prove that a complete local or graded one-dimensional
domain of prime characteristic has finite F-representation type if its
residue field is algebraically closed or finite, and present examples of
a complete local or graded one-dimensional domain which does not
have finite F-representation type with a perfect residue field. We also
present some examples of higher dimensional rings of finite
F-representation type.
