In addition, the antenna system should consist of three dipoles so that the measured field does not depend on the receipting polarization (a field isotropy).
To be more specific, let [Sigma](2, 3, 5) and [P.sup.3] be closed 3-manifolds with smooth (locally linear) actions of a finite group G, and let H be the isotropy subgroup of the action of G on [[Sigma].sup.3] and [P.sup.3] at x [element of] [[Sigma].sup.3] and y [element of] [P.sup.3] respectively such that the local representations at x and y are equivalent.
We are interested in this paper in the generalization of PCL to all inertial frames, i.e., the claim that the properties of isotropy and independence of the speed of the source are universal (flame-independent)(8) properties of the lightspeed.
The combination provides very high isotropy which produces highly uniform switching response and outstanding repeatability in all directions.
When observers discovered the cosmicbackground of microwave radio radiation 20 years ago, they were happy with its apparent smooth isotropy. In any direction they looked, they saw radiation of the same temperature, and that was good because they believed that the universe was homogenous and isotropic, and so the microwave background, which comes down to undisturbed from early times, should have been smooth.
Values typically higher than 0.3 for Str mean a high isotropy of surfaces [17], which is the case of this surface.
We expect that the isotropy parameter ([v.sub.0]) of all aforesaid distributions is also of certain importance and we graphically plot the results in Figure 6.
For d [greater than or equal to] 3 the isotropy groups of the action start being non-trivial, and the filtration of subspaces of constant orbits type in [S.sup.c.sub.n]([R.sup.d])/SO(d) is given by the horizontal arrows [i.sub.j] in diagram (2.7).
We have the following local global principle for isotropy of almost simple algebraic groups over infinite global fields.
For the elastic space axisymmetric contact problems, in the cylindrical coordinates (with the z-axis being positioned normal to the plane of isotropy), the fundamental equations can be rewritten in the following manner.
