A gravitational singularity, spacetime singularity, or simply singularity, is a theoretical condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically. As such, a singularity is by definition no longer part of the regular spacetime and cannot be determined by "where" or "when".
A coordinate singularity occurs when an apparent singularity or discontinuity occurs in one coordinate frame, which can be removed by choosing a different frame. An example of this is the apparent singularity at the 90 degree latitude in spherical coordinates. An object moving due north (for example, along the line 0 degrees longitude) on the ...
This function appears to have a singularity at z = 0, but if one factorizes the denominator and thus writes the function as = it is apparent that the singularity at z = 0 is a removable singularity and then the residue at z = 0 is therefore 0. The only other singularity is at z = 1.
It was found that the one at = is a coordinate singularity, meaning that it is an artifact of the particular system of coordinates that was used; while the one at = is a spacetime singularity and cannot be removed. [5]
Depending on the type of singularity in the integrand f, the Cauchy principal value is defined according to the following rules: . For a singularity at a finite number b + [() + + ()] with < < and where b is the difficult point, at which the behavior of the function f is such that = for any < and = for any >.
Singularity (system theory), in dynamical and social systems, a context in which a small change can cause a large effect Gravitational singularity, in general relativity, a point in which gravity is so intense that spacetime itself becomes ill-defined
Singularity functions have been heavily studied in the field of mathematics under the alternative names of generalized functions and distribution theory. [ 1 ] [ 2 ] [ 3 ] The functions are notated with brackets, as x − a n {\displaystyle \langle x-a\rangle ^{n}} where n is an integer.
It is the simplest type of non-removable singularity of such a function (see essential singularity). Technically, a point z 0 is a pole of a function f if it is a zero of the function 1/ f and 1/ f is holomorphic (i.e. complex differentiable ) in some neighbourhood of z 0 .
