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Computable Functions (PCF) is a typed functional language introduced by Gordon Plotkin in 1977, [1] based on previous unpublished material by Dana Scott.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 Haskell.
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).
In mathematics, in the field of abstract algebra, the structure theorem for finitely generated modules over a principal ideal domain is a generalization of the fundamental theorem of finitely generated abelian groups and roughly states that finitely generated modules over a principal ideal domain (PID) can be uniquely decomposed in much the same way that integers have a prime factorization.

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.
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".
The term domain is also commonly used in a different sense in mathematical analysis: a domain is a non-empty connected open set in a topological space. In particular, in real and complex analysis , a domain is a non-empty connected open subset of the real coordinate space R n {\displaystyle \mathbb {R} ^{n}} or the complex coordinate space C n ...
Sample partial autocorrelation function with confidence interval of a simulated AR(3) time series. Partial autocorrelation is a commonly used tool for identifying the order of an autoregressive model. [6] As previously mentioned, the partial autocorrelation of an AR(p) process is zero at lags greater than p.
