A designation "flow graph" that includes both the Mason graph and the Coates graph, and a variety of other forms of such graphs [7] appears useful, and agrees with Abrahams and Coverley's and with Henley and Williams' approach. [1] [2] A directed network – also known as a flow network – is a particular type of flow
In New Foundations (NF) and related set theories, a formula in the language of first-order logic with equality and membership is said to be stratified if and only if there is a function which sends each variable appearing in (considered as an item of syntax) to a natural number (this works equally well if all integers are used) in such a way that any atomic formula appearing in satisfies ...
The butterfly diagram show a data-flow diagram connecting the inputs x (left) to the outputs y that depend on them (right) for a "butterfly" step of a radix-2 Cooley–Tukey FFT algorithm. This diagram resembles a butterfly as in the Morpho butterfly shown for comparison, hence the name. A commutative diagram depicting the five lemma
A flowchart is described as "cross-functional" when the chart is divided into different vertical or horizontal parts, to describe the control of different organizational units. A symbol appearing in a particular part is within the control of that organizational unit.
Flow graph may refer to: Flow or rooted graph (graph theory), a graph in which a vertex has been distinguished as the root; Control-flow graph (computer science), a representation of paths through a program during its execution; Flow graph (mathematics), a directed graph linked to a set of linear algebraic or differential equations
Control flow diagram, a diagram to describe the control flow of a business process, process or program; Cumulative flow diagram, a tool used in queuing theory; Functional flow block diagram, in systems engineering; Data flow diagram, a graphical representation of the flow of data through an information system; Dynamic stock and flow diagram
In differential topology, a branch of mathematics, the Whitney conditions are conditions on a pair of submanifolds of a manifold introduced by Hassler Whitney in 1965.. A stratification of a topological space is a finite filtration by closed subsets F i, such that the difference between successive members F i and F (i − 1) of the filtration is either empty or a smooth submanifold of dimension i.
Mather gives the following definition of a stratified space. A prestratification on a topological space X is a partition of X into subsets (called strata) such that (a) each stratum is locally closed, (b) it is locally finite and (c) (axiom of frontier) if two strata A, B are such that the closure of A intersects B, then B lies in the closure of A.
