In computer science, Programming Computable Functions (PCF) is a typed functional language introduced by Gordon Plotkin in 1977, [1] based on previous unpublished material by Dana Scott. [ a ] It can be considered to be an extended version of the typed lambda calculus or a simplified version of modern typed functional languages such as ML or ...
Photonic-crystal fiber (PCF) is a class of optical fiber based on the properties of photonic crystals. It was first explored in 1996 at University of Bath, UK. It was first explored in 1996 at University of Bath, UK.

A commutative domain is a Dedekind domain if and only if the torsion submodule is a direct summand whenever it is bounded (M is bounded means rM = 0 for some r in R), . Similarly, a commutative domain is a Prüfer domain if and only if the torsion submodule is a direct summand whenever it is finitely generated (Kaplansky 1960).
The X11 PCF bitmap font file format Portable Compiled Format (PCF) is a bitmap font format used by X Window System in its core font system, and has been used for decades. PCF fonts are usually installed, by default, on most Unix -based operating systems, and are used in terminals such as xterm .
PCF theory is the name of a mathematical theory, introduced by Saharon Shelah , that deals with the cofinality of the ultraproducts of ordered sets. It gives strong upper bounds on the cardinalities of power sets of singular cardinals, and has many more applications as well. The abbreviation "PCF" stands for "possible cofinalities".
However, over a Dedekind domain the ideal class group is the only obstruction, and the structure theorem generalizes to finitely generated modules over a Dedekind domain with minor modifications. There is still a unique torsion part, with a torsionfree complement (unique up to isomorphism), but a torsionfree module over a Dedekind domain is no ...
