For example, the word "encyclopedia" is a sequence of symbols in the English alphabet, a finite set of twenty-six letters. Since a word can be described as a sequence, other basic mathematical descriptions can be applied. The alphabet is a set, so as one would expect, the empty set is a subset. In other words, there exists a unique word of ...
Combinatory logic is a notation to eliminate the need for quantified variables in mathematical logic.It was introduced by Moses Schönfinkel [1] and Haskell Curry, [2] and has more recently been used in computer science as a theoretical model of computation and also as a basis for the design of functional programming languages.
In the mathematical field of graph theory, a word-representable graph is a graph that can be characterized by a word (or sequence) whose entries alternate in a prescribed way. In particular, if the vertex set of the graph is V , one should be able to choose a word w over the alphabet V such that letters a and b alternate in w if and only if the ...
The words 1, r, r 2, ..., r n-1, s, sr, ..., sr n-1 are a normal form for the dihedral group Dih n with S = {s, r} and 1 as above. The set of words of the form x m y n for m,n ∈ Z are a normal form for the direct product of the cyclic groups x and y with S = {x, y}. The set of reduced words in S are the unique normal form for the free group ...
In this context, the terms string and number may be used interchangeably, since a number is actually a string of symbols, e.g. an English word (like the word "eleven" used in the paradox) while, on the other hand, it is possible to refer to any word with a number, e.g. by the number of its position in a given dictionary or by suitable encoding.

Capital One recommends using the format “One thousand, five hundred and 00/100” for writing out $1,500. That would make $1,200 look like “One thousand, two hundred and 00/100.”
Initially, k = 0. While k and m are less than N, compare S[k] (the k-th symbol of the string S) to S[m]. There are three possible outcomes: S[k] is equal to S[m]: append S[m] to the current collected symbols. Increment k and m. S[k] is less than S[m]: if we append S[m] to the current collected symbols, we'll get a Lyndon word. But we can't add ...
