The phrase "a certain subclass of" is correct and usable in written English.
It can be used when referring to a specific category or group within a broader classification, often in academic or technical contexts.
Example: "In the study of biology, we often focus on a certain subclass of organisms that exhibit unique adaptations."
Alternatives: "a specific category of" or "a particular type of".
A certain subclass of this consistent framework is analyzed here, further extended and finally, an efficient numerical implementation is proposed.
We introduce a certain subclass of harmonic multivalent functions defined by using a Ruscheweyh derivative operator.
We also prove that the results are sharp for a certain subclass of functions.
In addition, they show that a certain subclass of globally rigid graphs, trilateration graphs, can be constructed and localized in linear time.
The main purpose of the present paper is to derive the neighborhoods and partial sums of a certain subclass of starlike functions.
In this respect, observe that Kokonendji et al. (2004, Table 2) suggests that as p→+∞, members of a certain subclass of the family of Poisson-Tweedie mixtures tend to a Poisson law.
Because of the many independent duplications and multiplications of either or both the α- and β-tubulins functional specialization of a certain subclass for cytoskeletal, axonemal, A-, B-, or C-tubules, or any other distinct microtubule substructure cannot be inferred, as has been suggested by others.
The subtle difference of miR-21 in serum and PBMCs as GC diagnosis biomarkers discovered in our study could imply that there is a big chance that components other than serum and PBMCs (e.g., certain subclass of blood cells) may give even better results in GC diagnosis.
We establish a 1 1 correspondence between certain subclasses of these classes.
Brannan and Taha [6] (see also [7]) introduced certain subclasses of a bi-univalent function class σ similar to the familiar subclasses S ∗ and K of starlike and convex functions of order α ( 0 < α ≤ 1 ), respectively (see [8]).
Some inclusion and convolution properties of certain subclasses of meromorphic functions associated with a family of multiplier transformations, which are defined by means of the Hadamard product (or convolution), are investigated.
