The phrase "a certain set point" is correct and usable in written English.
It can be used when referring to a specific level or value that is established as a reference or target in various contexts, such as science, psychology, or goal-setting.
Example: "In behavioral psychology, individuals often return to a certain set point of happiness after experiencing fluctuations in their mood."
Alternatives: "a specific reference point" or "a defined target level".
In this constructive topology the role of open sets and points is reversed; in classical topology an open set is defined as a certain set of points, in the constructive case open sets are the fundamental notion and points are defined in terms of them.
It involves a certain set of points on a plane that correspond to solutions that make an equation, the zeta function, equal zero.
Let's say I give you the equation x 2y 3z = 0. OK, so that defines a certain set of points in space, and what do you think the set of solutions look like if I give you this equation?
Recently, an extension to separable multivariate problems has been given; in this context, the authors have found a matrix representation of the quantum angular momentum, yielding the precise eigenvalues and finite-dimensional vectors that coincide exactly with the spherical harmonics evaluated at a certain set of points.
An inverse procedure is used to optimize the coil's characteristics, subject to the restrictions imposed by the desired field behavior over a certain set of constraint points inside a predetermined imaging volume.
An intermediate step is the approximation G x,y)≈∣∣x−y∣∣α−dg(x g y)/g(A 2, where A is an arbitrary point in a certain set B x,y).
"We are really focused on a certain set of key milestones at this point and I originally put it out to do the round at $750k.
While a certain set of site symmetries constitutes a point symmetry group in the Euclidian plane and requires a compatible translation symmetry type, a certain translation symmetry type enables a few sets of site symmetries in 2D-periodic images.
The Koch brothers are well-known at this point among a certain set.
