52Profanity in American sign language — American Sign Language, the sign language used by the Deaf Community throughout most of North America, has a rich vocabulary of terms which include profanity. Within Deaf culture, there is a distinction drawn between signs used to curse versus… …
53Stream function — The stream function is defined for two dimensional flows of various kinds. The stream function can be used to plot streamlines, which represent the trajectories of particles in a steady flow. Streamlines are perpendicular to equipotential lines.… …
54Artin L-function — In mathematics, an Artin L function is a type of Dirichlet series associated to a linear representation ρ of a Galois group G . These functions were introduced in the 1923 by Emil Artin, in connection with his research into class field theory.… …
55Plus-minus sign — For other uses, see plus minus (disambiguation). ± The plus minus sign (±) is a mathematical symbol commonly used either to indicate the precision of an approximation, or to indicate a value that can be of either sign. The sign is normally… …
56Zonal spherical function — In mathematics, a zonal spherical function or often just spherical function is a function on a locally compact group G with compact subgroup K (often a maximal compact subgroup) that arises as the matrix coefficient of a K invariant vector in an… …
57Conway base 13 function — The Conway base 13 function is a function created by British mathematician John H. Conway as a counterexample to the converse of the intermediate value theorem. In other words, even though Conway s function f is not continuous, if… …
58Hermitian function — In mathematical analysis, a Hermitian function is a complex function with the property that its complex conjugate is equal to the original function with the variable changed in sign::f( x) = overline{f(x)}for all x in the domain of of f. This… …
59Quantile function — See also quantile. In probability theory, a quantile function of a probability distribution is the inverse F −1 of its cumulative distribution function (cdf) F . Assuming a continuous and strictly monotonic distribution function, scriptstyle… …
60Liouville function — The Liouville function, denoted by λ( n ) and named after Joseph Liouville, is an important function in number theory. If n is a positive integer, then λ( n ) is defined as::lambda(n) = ( 1)^{Omega(n)},,! where Omega;( n ) is the number of prime… …
