The main gravitational attractor in the mapped area is the Virgo Cluster, with 600 trillion times the mass of the Sun, 50 million light years from us.
For all the elements of national security there is an independent threat attractor, for example food autarky can have availability of water and arable land as a threat attractor.
The attract method was applied to determine the attractor modules that were identified by the clique-merging algorithm.
Our Local Group is moving toward what's called the Great Attractor, a dense collection in the vicinity of the Centaurus, Norma, and Hydra clusters about 160 million light-years away.
For any positive parameters [alpha], [lambda], [gamma], g, [epsilon], any [([[phi].sub.0], [[psi].sub.0]).sup.T] [member of] [L.sup.2]([OMEGA]) x [H.sup.2]([OMEGA]), and n [less than or equal to] 3, there exists a global attractor A in the phase space [L.sup.2]([OMEGA]) x [H.sup.2]([OMEGA]) for the solution semiflow [{S(t)}.sub.t [greater than or equal to] 0] on [L.sup.2]([OMEGA]) x [H.sup.2]([OMEGA]) generated by system (1.1)-(1.2) with the Neumann boundary conditions (1.3).
Since the coefficients ([a.sub.0], [a.sub.1], [a.sub.2], [a.sub.3]) were constant in these calculations, the fulfillment of the convergence condition indicated the fundamental stability of the corresponding state of the world economy regardless of whether this stable state was a fixed stable point or it was dynamically stable (a limit cycle or a strange attractor).
Volume one of the two-volume set introduces the global attractor and estimation of Hausdorff and fractal dimensions for some dissipative nonlinear evolution equations in modern physics, explores the existence and smoothness of inertial manifolds, and uses the two-dimensional Navier-Stokes equations as an example to illustrate the variety of approximate inertial manifolds and their error estimation.
All comparison algorithms are listed in Table 3, where the InfoMap, FastGreedy and Louvain algorithms are considered to be the best algorithms for disjoint community detection [3,21], the LPA algorithm has a high speed, and the Attractor algorithm is a native algorithm built on the distance dynamics model.
