  Mathematical singularity - Wikipedia, the free encyclopedia
In mathematics, a singularity is in general a point at which a given mathematical object is not defined, or a point of an exceptional set where it fails to be well-behaved in some particular way, such as differentiability.
In algebraic geometry and commutative algebra, a singularity is a prime ideal whose localization is not a regular local ring (alternately a scheme (mathematics) with a stalk that is not a regular local ring).
In linear algebra a square matrix is said to be singular when it is not invertible, that is when its determinant is zero.

Not withstanding the power of mathematics, scientific analysis must also be unequivocally bound to such rigorous human logic, that, it is deemed to be of an axiomatic nature and it should only be supported by mathematical calculations to maintain precision and logical continuity.
The singular element in the midst of an infinite sea of such components cannot at all have the freedom to move, transfer or translocate in any manner whatsoever in a relative way or in other words each component is always at rest relative to each other.
Any mathematical description of phenomenon in physics etc. is based on movement or displacement and therefore a definition of singularity reflects the state of its movement, whereas the holographic Purusha cannot move in any way.

 The Singularity   (Site not responding. Last check: 2007-11-06)
The "Singularity" was a term originally coined by Vernor Vinge, a mathematician and science-fiction author, to describe the breakdown in our predictions of the future that occurs when some form of greater-than-human intelligence comes into play - the moment when human intelligence, the source of technology, is improved by that technology.
The term "Singularity" was coined by Vinge in analogy with the singularity at a center of a fl hole, where our current understanding of physics breaks down; beyond the point where transhuman intelligence exists, our model of the future breaks down.
Vernor Vinge's original definition of the Singularity is probably the most important, since it captures the essential idea of a change that is different in kind from any that humanity has previously experienced.

An example of simple mathematical singularity is the point when x = 1 in 1/(x-1) It simply means that at that point the value of x is indefinite.
In fact the singularities in elementary particle theories have been removed by normalization process in Physics so that we could still handle the Physics with laws that we are familiar with.
Singularity is therefore the greatest argument for the existence of God beyond this physical universe.

Singularities arise naturally in a huge number of different areas of mathematics and science.
The main goal in most problems of singularity theory is to understand the dependence of some objects of analysis and geometry, or physics, or from some other science on parameters.
In spite of its fundamental character, and the central position it now occupies in mathematics, singularity theory is a surprisingly young subject.

 A Comment on the Singularity
A "tech Singularity" is a projected brief interval of time in which the practical innovation rate becomes so fast as to seem essentially instantaneous to humans.
The Singularity will probably be brought about by the convergence of a large number of interrelated technologies, a process that Kurzweil has described very well.
On the other hand, the Singularity may be a multifurcation point, so that a small nudge in one direction or another can have a big effect on what path is taken.

Ungoverned AI progress will resemble a singularity as far as human scope and time scale are concerned, and result in a new regime with properties that are not simply an extrapolation of what happened before the "singularity".
RAY: Yes, I understand that, and I use the term "singularity" in this sense, that is a "rupture" in the fabric of human history caused by the cycle of strong AI (nonbiological intelligence) having access to its own source code and improving it.
However, I am not definining the technological "singularity" as a mathematical singularity, but (like Vinge) using the word as a metaphor for an event with an event horizon beyond which it is difficult to penetrate (analogously with a fl hole).

 Singularities in Mathematical Models   (Site not responding. Last check: 2007-11-06)
The term `singularity' is used in applied mathematics to indicate that a conventional way of modelling a certain physical process mathematically leads to consequences which for some reasons cannot be accepted.
If a solution exists but some physical arguments indicate a `singularity', one has to find out whether it appeared due to simplifications and/or additional assumptions made in the process of obtaining the solution (see [1] for a review of such cases) or whether it is inherent in the very formulation of the problem.
A standard remedy for the singularity is to use `microscopic cutoffs' to stop the solution on its way to the singularity which is inherent in the very formulation of the problem.

 What is the Technological Singularity?
The Technological Singularity, or simply "Singularity," is a multi-faceted concept in futurism with several overlapping and sometimes conflicting definitions.
The term "Technological Singularity" was coined by analogy to the singularity in the center of a fl hole, where the forces of nature become so intense and unpredictable that our ability to calculate the behavior of matter in these circumstances drops to zero.
However, this notion of the singularity is not the same as Vinge intended; referring to the emergence of superhuman intelligence, along with superhuman thinking speeds.

 Paradoxes Resolved, Origins Illuminated - Black holes
They were based on an extra mathematical singularity in the spacetime metric that occurred because Einstein truncated an expansion in potential to first order, seeing no point in retaining second-order effects that were far beyond any conceivable means of detection at that time.
The first singularity is at the origin when distance goes to zero, and can be avoided by the finite size of masses.
This second singularity corresponds to what we now call the "event horizon" and cannot be eliminated in the present form of the equations.

 Paths to the Singularity
This not actually a mathematical singularity, but the rate of progress will become so fast over such a short amount of time that there is no effective difference.
I believe that the singularity will occur when a technology-based entity comes into existence that is modestly more intelligent than the most intelligent human, with "intelligence" defined as "technical creativity." Since this entity is technology-based and technically creative, it can immediately increase its own capabilities in a rapid feedback loop.
However, by the time of the singularity, the network will be an essential element of nearly all economic activity, so the shutdown will create havoc and is likely to result in civil unrest or warfare.

In this, T0 is "present" or the mathematical singularity, and t1 is the time of the event when we started the evaluation.
But, it appears that actually it’s not necessary, but mathematically it is. This is because it still is required (remember we still have to do the outside observer, so we have to take everything in account).
But, in order to keep them correct, mathematically speaking, we have to assume that some physical change happens when we are at this point on the evolution of t+.

In a rotating fl hole, the singularity occurs on a ring, and is called a "ring singularity".
However, in 1991 Shapiro and Teukolsky performed computer simulations of a rotating plane of dust which indicated that general relativity allows for naked singularities.
It is generally assumed that a theory of quantum gravity - a theory that unifies general relativity with quantum mechanics - will provide a better description of what actually occurs where general relativity predicts a singularity.

To a physicist they are also appealing because their mathematical formulation is in many senses unique: it has to self-consistently describe the flow inside each of the fluids (water, air) as well as the motion of their interface.
One peculiarity is due to a discontinuous change in the physical properties of the fluids at the interface, which shows up as a mathematical singularity in the equations of fluid motion.
Such changes are usually associated with the appearance of an additionional singularity - in the curvature of the interface.

The major issue is not that a mathematical singularity exists in a theory, but the physical meaning of that singularity.
You cannot enrich mathematics in relation with nature, because while the former is abstract, our knowledge of the latter is empirical, obeyng rules that are not mathematical in essence.
What matters is only the meaning of the mathematical symbols, and physics assumes its right to use math as it sees fit, and within limits that are not mathematical in nature.
