2 unusual facts about Finite


Extended Affix Grammar

The remedy proposed was to switch to the much simpler Affix Grammar over a Finite Lattice (AGFL) instead, in which metagrammars can only produce simple finite languages.

Finite

Finite set, whose cardinality (number of elements) is some natural number

For example, the circle method of Hardy and Littlewood was conceived as applying to power series near the unit circle in the complex plane; it is now thought of in terms of finite exponential sums (that is, on the unit circle, but with the power series truncated).

Approximate finite dimensionality was first defined and described combinatorially by Bratteli.

Discontinuous Deformation Analysis

An example of this approach is the research by Chang et al. and also Jing who resolved this problem by adding finite element meshes in the two-dimensional domain of the blocks so that stress variations within the blocks can be allowed.

Explicit formula

Algebraic expression, a mathematical expression in terms of a finite number of algebraic operations (addition, subtraction, multiplication, division and exponentiation by a rational exponent)

Analytical expression, a mathematical expression in terms of a finite or infinite number of well-known functions

Closed-form expression, a mathematical expression in terms of a finite number of well-known functions

Family of sets

Hall's marriage theorem, due to Philip Hall gives necessary and sufficient conditions for a finite family of non-empty sets (repetitions allowed) to have a system of distinct representatives.

Field Commander

Fuel and ammunition are finite for vehicles and primary weapons, while infantry have unlimited fuel and secondary weapons have unlimited ammunition.

Finite dimensional von Neumann algebra

The finite dimensional case differs from the general von Neumann algebras in that topology plays no role and they can be characterized using Wedderburn's theory of semisimple algebras.

Finite geometry

For finite projective spaces of geometric dimension at least three, Wedderburn's little theorem implies that the division ring over which the projective space is defined must be a finite field, GF(q), whose order (that is, number of elements) is q (a prime power).

In 1892, Gino Fano was the first to consider such a finite geometry – a three dimensional geometry containing 15 points, 35 lines, and 15 planes, with each plane containing 7 points and 7 lines.

Those most popular in the literature are three-valued (e.g., Łukasiewicz's and Kleene's, which accept the values "true", "false", and "unknown"), the finite-valued with more than three values, and the infinite-valued, such as fuzzy logic and probability logic.
