In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
Formal logic (also known as symbolic logic) is widely used in mathematical logic. It uses a formal approach to study reasoning: it replaces concrete expressions with abstract symbols to examine the logical form of arguments independent of their concrete content. In this sense, it is topic-neutral since it is only concerned with the abstract ...
The symbolic code produces a structure of (often paired) symbolic meanings that accumulate throughout the text to establish a larger structure in which the meanings of the story unfold. These symbolic clusters of meanings might be around such oppositions as male/female, inside/outside, hidden/revealed, hot/cold.
Mathematical logic, also called 'logistic', 'symbolic logic', the 'algebra of logic', and, more recently, simply 'formal logic', is the set of logical theories elaborated in the course of the nineteenth century with the aid of an artificial notation and a rigorously deductive method. [5]
A diploma from the Masonic Grande Loge de France showing the symbol as a substitute for the dot of abbreviation. In Freemasonry traditions, the symbol is used to indicate a Masonic abbreviation (rather than the period mark used conventionally with some abbreviations). For example, "R∴W∴ John Smith" is an abbreviation for "Right Worshipful ...
Symbolic computation, a scientific area concerned with computing with mathematical formulas; Symbolic dynamics, a method for modeling dynamical systems by a discrete space consisting of infinite sequences of abstract symbols; Symbolic execution, the analysis of computer programs by tracking symbolic rather than actual values
The most obvious way to define a graph is a structure with a signature consisting of a single binary relation symbol . The vertices of the graph form the domain of the structure, and for two vertices a {\displaystyle a} and b , {\displaystyle b,} ( a , b ) ∈ E {\displaystyle (a,b)\!\in {\text{E}}} means that a {\displaystyle a} and b ...
