Wikimedia Commons. Indicates the functional nature of an expression without assigning a specific symbol for an argument.
Contour integral; closed line integral contour integral of calculus. Similar to the integral, but used to denote a single integration over a closed curve or loop.
It is sometimes used in physics texts involving equations regarding Gauss's Law , and while these formulas involve a closed surface integral , the representations describe only the first integration of the volume over the enclosing surface.
Sometimes used in proofs before logical consequences. The statement! A is true if and only if A is false. A slash placed through another operator is the same as "!
The symbol! Computer scientists will often use! The forms! Assignment is defined to be everywhere. This is I. Vinogradov 's notation. Karp reduction is Karp reducible to; is polynomial-time many-one reducible to computational complexity theory.
Nondominated order is nondominated by Multi-objective optimization. Converse implication.. This reads as "a if b", or "not b without a". It is not to be confused with the assignment operator in computer science.
The body of a piecewise-defined function can have any finite number not only just two expression-condition pairs. This symbol is also used in type theory for pattern matching the constructor of the value of an algebraic type.
A pattern matching can have any finite number not only just two pattern-expression pairs. Euclidean norm or Euclidean length or magnitude Euclidean norm of geometry.
X means the cardinality of the set X. This may also be written [ x ], floor x or int x. This may also be written ceil x or ceiling x. This may also be written [ x ], x , nint x or Round x.
Not to be confused with the nearest integer function, as described below. Not to be confused with the floor function, as described above.
Iverson bracket 1 if true, 0 otherwise propositional logic. This may also be written as f X if there is no risk of confusing the image of f under X with the function application f of X.
Another notation is Im f , the image of f under its domain. This may also be written as f [ X ] if there is a risk of confusing the image of f under X with the function application f of X.
An ordered list or sequence, or horizontal vector, or row vector of values. This may also be written hcf a , b or gcd a , b. These are avoided in mathematical texts.
That is, it is the intersection of all subspaces of V which contain S. The notation a , b is often used as well.
Hodge star operator Hodge star; Hodge dual linear algebra. Other sets can be used in place of R. Kleene star Kleene star computer science , mathematical logic.
The full set cannot be enumerated here since it is countably infinite , but each individual string must have finite length. Karp reduction  is Karp reducible to; is polynomial-time many-one reducible to computational complexity theory.
P A B means the probability of the event A occurring given that B occurs. A B is the connected sum of the manifolds A and B.
If A and B are knots, then this denotes the knot sum, which has a slightly stronger condition. A S m is homeomorphic to A , for any manifold A , and the sphere S m.
See also bra—ket notation. The index of a subgroup H in a group G is the "relative size" of H in G : equivalently, the number of "copies" cosets of H that fill up G.
Denotes that certain constants and terms are missing out e. This may also be written A wr H. Denotes that contradictory statements have been inferred.
For clarity, the exact point of contradiction can be appended. The direct sum is a special way of combining several objects into one general object.
Kulkarni—Nomizu product Kulkarni—Nomizu product tensor algebra. Derived from the tensor product of two symmetric type 0,2 tensors ; it has the algebraic symmetries of the Riemann tensor.
A symbol Semiotics is the study of signs, symbols, and signification as communicative behavior. Semiotics studies focus on the relationship of the signifier and the signified, also taking into account the interpretation of visual cues, body language, sound, and other contextual clues.
Semiotics is linked with both linguistics and psychology. Semioticians thus not only study what a symbol implies but also how it got its meaning and how it functions to make meaning in society.
Symbols allow the human brain continuously to create meaning using sensory input and decode symbols through both denotation and connotation.
An alternative definition of symbol , distinguishing it from the term sign was proposed by Swiss psychoanalyst Carl Jung. In his studies on what is now called Jungian archetypes , a sign stands for something known, as a word stands for its referent.
He contrasted a sign with a symbol : something that is unknown and that cannot be made clear or precise.
An example of a symbol in this sense is Christ as a symbol of the archetype called self. Kenneth Burke described Homo sapiens as a " symbol-using, symbol making, and symbol misusing animal " to suggest that a person creates symbols as well as misuses them.
One example he uses to indicate what he means by the misuse of symbol is the story of a man who, when told that a particular food item was whale blubber, could barely keep from throwing it up.
Later, his friend discovered it was actually just a dumpling. But the man's reaction was a direct consequence of the symbol of "blubber" representing something inedible in his mind.
In addition, the symbol of "blubber" was created by the man through various kinds of learning. Burke goes on to describe symbols as also being derived from Sigmund Freud 's work on condensation and displacement , further stating that symbols are not just relevant to the theory of dreams but also to "normal symbol systems".
He says they are related through "substitution", where one word, phrase, or symbol is substituted for another in order to change the meaning.
However, upon learning the new way of interpreting a specific symbol, the person may change his or her already-formed ideas to incorporate the new information.
Jean Dalby Clift says that people not only add their own interpretations to symbols, they also create personal symbols that represent their own understanding of their lives: what she calls "core images" of the person.
She argues that symbolic work with these personal symbols or core images can be as useful as working with dream symbols in psychoanalysis or counseling.
William Indick suggests that the symbols that are commonly found in myth, legend, and fantasy fulfill psychological functions and hence are why archetypes such as "the hero," "the princess" and "the witch" have remained popular for centuries.
Symbols can carry symbolic value in three primary forms: Ideological, comparative, and isomorphic. Comparative symbols such as prestigious office addresses, fine art, and prominent awards indicate answers to questions of "better or worse" and "superior or inferior".
Isomorphic symbols blend in with the surrounding cultural environment such that they enable individuals and organizations to conform to their surroundings and evade social and political scrutiny.
Examples of symbols with isomorphic value include wearing a professional dress during business meetings, shaking hands to greet others in the West, or bowing to greet others in the East.
A single symbol can carry multiple distinct meanings such that it provides multiple types of symbolic value.
Paul Tillich argued that, while signs are invented and forgotten, symbols are born and die. A living symbol can reveal to an individual hidden levels of meaning and transcendent or religious realities.
For Tillich a symbol always "points beyond itself" to something that is unquantifiable and mysterious; symbols open up the "depth dimension of reality itself".
When a symbol loses its meaning and power for an individual or culture, it becomes a dead symbol. When a symbol becomes identified with the deeper reality to which it refers, it becomes idolatrous as the "symbol is taken for reality.
The unique nature of a symbol is that it gives access to deeper layers of reality which are otherwise inaccessible. A symbol's meaning may be modified by various factors including popular usage, history , and contextual intent.
The history of a symbol is one of many factors in determining a particular symbol's apparent meaning.
Consequently, symbols with emotive power carry problems analogous to false etymologies. The context of a symbol may change its meaning.
Similar five-pointed stars might signify a law enforcement officer or a member of the armed services , depending upon the uniform. Symbols are used in cartography to communicate geographical information generally as point, line, or area features.
Map symbols can thus be categorized by how they suggest this connection:  . A symbolic action is an action that has no, or little, practical effect but symbolizes, or signals, what the actor wants or believes.
The action conveys meaning to the viewers. Symbolic action may overlap with symbolic speech , such as the use of flag burning to express hostility or saluting the flag to express patriotism.
