Is fisheries plural or singular?
The noun fishery can be countable or uncountable. In more general, commonly used, contexts, the plural form will also be fishery. However, in more specific contexts, the plural form can also be fisheries e.g. in reference to various types of fisheries or a collection of fisheries.
Why plural of fish is fish?
The most common plural form of fish is indeed fish. However, under certain circumstances, you can use fishes as the plural form of fish. Fish can refer to multiple fish, especially when they are all the same species of fish. Fishes, however, usually refers to multiple species of fish, especially in scientific contexts.
Why fish has no plural?
Fishes is plural form of fish. However fish is used in both singular and plural forms because fishes is generally used to represent different species.
What is the singular of means?
When a means is a single practice, it’s singular—for example, “The best means of keeping teeth clean is to brush twice daily.” When means denotes multiple practices, it’s plural—for example, “Some means of finding jobs are more effective than others.”
What is singular example?
If you look at one object and name it, you have an example of a singular noun. For example there is one lamp on my bookcase and one chair at my desk. In these examples the nouns lamp, bookcase, chair, and desk are all singular because they indicate only one.
What is singular set example?
The singular set Σ has a simple structure in dimension 3, since then it is composed of isolated point. Lin [108] proved that the singular set Σ of a minimizer in W1,2 (B4, S2) with a smooth trace on ∂B4 is the union of a finite set and of finitely many Hölder continous closed curves with only finitely many crossings.
What is singular mapping?
A linear mapping T: V W is said to be singular if it maps some nonzero vector in V into 0 W. If it maps only 0 V into 0. W it is said to be nonsingular. A mapping is inonsingular if and only if it is one-to-one. A nonsingular mapping possesses an inverse; a singular mapping does not.
What is singular set explain with example in DBMS?
The singular set of a variety X is the set of singular points . This is a proper subvariety. A subvariety Y of X is contained in the singular set if and only if its local ring.
What is a singular point of a function?
Singularity, also called singular point, of a function of the complex variable z is a point at which it is not analytic (that is, the function cannot be expressed as an infinite series in powers of z) although, at points arbitrarily close to the singularity, the function may be analytic, in which case it is called an …
What is a singular limit?
A singular limit is also sometimes called a “discontinuous limit” and it means that if some variable gets closer to a certain point, you do not get a good approximation for the value of a function at this point. The function is what you could call the yuckiness of the apple.
How do you find the singular point?
9.1. Finding Singular Points
- p(x) = Q(x)/P(x)
- q(x) = R(x)/P(x)
- the singular points occur where Q(x)/P(x) and/or R(x)/P(x) become unbounded.
Are zeros singularities?
In complex analysis (a branch of mathematics), a pole is a certain type of singularity of a function, nearby which the function behaves relatively regularly, in contrast to essential singularities, such as 0 for the logarithm function, and branch points, such as 0 for the complex square root function.
Can 0 be a polynomial?
Like any constant value, the value 0 can be considered as a (constant) polynomial, called the zero polynomial. It has no nonzero terms, and so, strictly speaking, it has no degree either. As such, its degree is usually undefined.
How do you find order of zeros?
A zero is of order n if 0 = f (z0) = f (z0) = ··· = f(n−1)(z0), but f(n)(z0) = 0. A zero of order one (i.e., one where f (z0) = 0) is called a simple zero. Examples: (i) f(z) = z has a simple zero at z = 0.
What is singularity at infinity?
Definition (Isolated Singularity at Infinity): The point at infinity z = ∞ is called an isolated singularity of f(z) if f(z) is holomorphic in the exterior of a disk {z ∈ C : |z| > R}. (b) f(z) has a pole of order m ≥ 1 at z = ∞ if f(1/z) has a pole of order m ≥ 1 at z = 0.
How do you identify a singularity?
There are basically three types of singularities (points where f(z) is not analytic) in the complex plane. An isolated singularity of a function f(z) is a point z0 such that f(z) is analytic on the punctured disc 0 < |z − z0| < r but is undefined at z = z0. We usually call isolated singularities poles.
How do you know if a singularity is removable?
f has an isolated singularity at z = a if there is a punctured disk B(a, R)\{a} such that f is defined and analytic on this set, but not on the full disk. a is called removable singularity if there is an analytic g : B(a, R) → C such that g(z) = f(z) for 0 < |z − a| < R. Investigation of removable singularities.
What is the singularity theory?
In technology, the singularity describes a hypothetical future where technology growth is out of control and irreversible. These intelligent and powerful technologies will radically and unpredictably transform our reality.
Will Singularity arrive eventually?
Kurzweil believes that the singularity will occur by approximately 2045. His predictions differ from Vinge’s in that he predicts a gradual ascent to the singularity, rather than Vinge’s rapidly self-improving superhuman intelligence.
What happens inside a singularity?
According to theory, within a black hole there’s something called a singularity. A singularity is what all the matter in a black hole gets crushed into. In a very specific mathematical case, the singularity in a spinning black hole becomes a ring, not a point. But that mathematical situation won’t exist in reality.
