The phrase "abstract approximation" is correct and usable in written English.
It can be used in contexts where you are discussing theoretical models or concepts that simplify complex ideas or phenomena.
Example: "In our research, we developed an abstract approximation of the system to better understand its underlying dynamics."
Alternatives: "theoretical estimation" or "conceptual approximation".
The rationale is that by knowing statistical rules of thumb for the way in which words are usually put together an abstract probabilistic approximation of grammar, if you will it is possible to narrow the search when attempting to identify individual words.
For more details on abstract Korovkin approximations theory, we refer to [3] and [4].
In a general semantic account, Sarkar distinguishes different kinds of reduction in terms of four criteria, two epistemological and two ontological: fundamentalism, approximation, abstract hierarchy and spatial hierarchy.
In abstract interpretation-based static analysis, approximation is encoded by abstract domains.
As a first approximation, economists can abstract from such difficulties caused by the intentionality of belief and desire.
These themes include Euclidean geometry, optics, rational and irrational numbers, linear perspective and chaos theory, though in most cases the visual representations are only vague approximations of these abstract, complex concepts.
The roots of this theory go back to the famous works of Brouwer (1912) and Banach (1922), the latter author gave an abstract formulation of the successive approximations method, systematically used by Liouville (1837) in his results.
Mathematics is also a science which considers abstract concepts, but even in this theoretical science approximation occurs (the examples are that of the impossibility of squaring a circle and the approximation in writing an irrational number).
The Alan Parsons Project's Pyramid (1978) was fronted by portrait of a solitary figure in a hotel bedroom, riven with a huge abstract, blue blob of interference, as near to an approximation of a migraine as any visual artist has probably ever managed.
In this paper, we generalize Steinʼs method to "infinite-variate" normal approximation that is an infinite-dimensional approximation by abstract Wiener measures on a real separable Banach space.
