The phrase "a compact group of" is correct and usable in written English.
It can be used to describe a small, closely-knit collection of people, objects, or entities.
Example: "The conference was attended by a compact group of experts in the field, fostering in-depth discussions."
Alternatives: "a small cluster of" or "a tight-knit group of".
They consist of a compact group of radial ridges averaging from 6,000 to 8,800 feet (1,800 to 2,700 metres) in elevation.
While the Saudi proposal would allow Israel to retain Jewish religious sites and residential areas in Jerusalem and even apparently to hold on to a compact group of settlements just beyond the 1967 lines in exchange for equivalent territory elsewhere, a substantial evacuation of West Bank settlements would be required.
Moreover, Let G be a compact group of (linear) unitary transformation on a real Hilbert space H.
Let Hn be the (2n+1 -dimensional Heisenberg group and K a compact group of automorphisms of Hn such that (K⋉Hn,K) is a Gelfand pair.
Let G⊂O(n) be a compact group of isometries acting on n-dimensional Euclidean space Rn, and X a bounded domain in Rn which is transformed into itself under the action of G. Consider a symmetric, classical pseudodifferential operator A0 in L2(Rn) with G-invariant Weyl symbol, and assume that it is semi-bounded from below.
In this Note, we state a polynomial characterization of weakly invariant designs and show how to derive the construction of weakly invariant designs for the action of a compact group of matrices on an experimental domain, whose interior is not empty, from the construction of rotatable designs.
In representation theory, the Peter Weyl theorem guarantees that any unitary representation of a compact group on a Hilbert space splits as the direct sum of finite-dimensional representations.
We first prove that for a coaction of a compact group on a C∗-algebra A, the largest liminal (resp. postliminal) ideal of A is invariant under the coaction.
(I) If (X) is Hausdorff, then any action of a compact group on (X) is proper.
William granted some lands to his continental followers from the holdings of one or more specific Englishmen; at other times, he granted a compact grouping of lands previously held by many different Englishmen to one Norman follower, often to allow for the consolidation of lands around a strategically placed castle.
The same holds true for G-weakly invariant designs, G being any compact group of matrices.
