The result of combining an absorbing element with any element of the set is the absorbing element itself. In semigroup theory, the absorbing element is called a zero element [1] [2] because there is no risk of confusion with other notions of zero, with the notable exception: under additive notation zero may, quite naturally, denote the neutral ...
An absorbing element in a multiplicative semigroup or semiring generalises the property 0 ⋅ x = 0. Examples include: The empty set, which is an absorbing element under Cartesian product of sets, since { } × S = { } The zero function or zero map defined by z(x) = 0 under pointwise multiplication (f ⋅ g)(x) = f(x) ⋅ g(x)
In mathematics, a null semigroup (also called a zero semigroup) is a semigroup with an absorbing element, called zero, in which the product of any two elements is zero. [1] If every element of a semigroup is a left zero then the semigroup is called a left zero semigroup; a right zero semigroup is defined analogously. [2]
So where is all this negative energy today? It's in the third ingredient in our cosmic cookbook: it's in space. This may sound odd, but according to the laws of nature concerning gravity and motion—laws that are among the oldest in science—space itself is a vast store of negative energy. Enough to ensure that everything adds up to zero. [14]
In his essay Nature, the metaphor stands for a view of life that is absorbent rather than reflective, and therefore takes in all that nature has to offer without bias or contradiction. Emerson intends that the individual become one with nature, and the manner of the transparent eyeball is an approach to achieving it.
The question for the Chicago School (as it was for Aristotle) was always what the purpose of the theory of criticism was, what hypotheses were brought to bear by the theory about the nature of literature (for instance, whether it consisted of the words alone, or whether it was to be thought of as part of a larger context such as an era or an artist's life), and the definitions of words (such ...
In comparison with other 'political' forms of criticism, there has been relatively little dispute about the moral and philosophical aims of ecocriticism, although its scope has broadened from nature writing, romantic poetry, and canonical literature to take in film, television, theatre, animal stories, architectures, scientific narratives and an extraordinary range of literary texts.
In general relativity, a vacuum solution is a Lorentzian manifold whose Einstein tensor vanishes identically. According to the Einstein field equation, this means that the stress–energy tensor also vanishes identically, so that no matter or non-gravitational fields are present.
