Two examples of nets in analysis 11 3.3. De nition 1.9. topology (point-set topology, point-free topology) ... (which is a primitive concept in convergence spaces). The convergence of nets is de ned analogously to the usual notion of convergence of sequences. This does not hold in an arbitrary topological space, and Mariano has given the canonical counterexample. Convergence of the ring topologies are generally slow compared to other alternatives such as partial mesh, full-mesh and diverge planes topologies. FIGURE-1 Figure-1 is traditional ring topology, adding a new node is fairly simple, traffic flow is predictable and with dual-ring redundancy resiliency can be improved. In this chapter we develop a theory of convergence that is sufficient to describe the topology in any space . For information on this, see e.g. Nets and subnets 7 3.2. This is the beginning of more penetrating theories of convergence given by nets and/or filters. Sequential spaces 6 3. Convergence and sub net of a g-net are defined the way it is done for a net in topology [13]. In a metric (or metrizable) space, the topology is entirely determined by convergence of sequences. In this chapter we develop a theory of convergence that is sufficient to describe the topology in any space . Apart from this minor problem, the notion of convergence for nets is modeled after the corresponding one for ultra lters, having in mind the examples 2.2.B-D above. A convergence structure in a set X is a class Cof tuples ((x i) i2I;x) where (x i) i2I is a net whose terms are elements of X and x 2X. It is denoted by (x d) d2D. In Section 5, we … Let (x d) d2D be a net … Finally, we introduce the concept of -convergence and show that a space is SI2 -continuous if and only if its -convergence with respect to the topology τSI2 ( X ) is topological. Definition. fDEFLIMNETg De nition 1.10. By the weak topology of M(G) we mean the topology of pointwise convergence on L(G); that is, given a net {μ i} of elements sof M(G), we have μ i → μ weakly if and only if I μi (f) → i I μ (f) for every f in L(G).

Arbitrary topological spaces 4 2.2. Introduction: Convergence Via Sequences and Beyond 1 2. (Here I μ is the complex integral corresponding to μ as in II.8.10.). We define a kind of “generalized sequence” called a A sequence is a function ,\Þ0−\net and we write A net is a function 0Ð8ÑœBÞ 0−\ Ð ßŸÑ8 A, where is a more general kind ofA ordered set. 10.17.

Let (X;T) be a topological space, and let (x ) 2 be a net in X. Also there are other changes like the addition of switch or failure of port of an existing switch. Given a point x2X, we say that the net (x ) 2 is convergent to x, if it is a Topology. For each of order convergence, unbounded order convergence, and—when applicable—convergence in a Hausdorff uo-Lebesgue topology, there are two conceivable implications between uniform and strong convergence of a net of order bounded operators. Once the Spanning Tree Topology (STP) is established, STP continues to work until some changes occurs. Nets 7 3.1.
