Web(R;discrete topology) !(R;natural topology) : In an abelian category, the failure of this map to be an isomorphism has to be explained by a nontrivial kernel or cokernel. Note that this example is not pathological: We certainly want to include all abstract discrete abelian groups, as well as R, and we certainly want WebTo describe curves on it, one natural idea is to choose once for all a collection of curves as a reference system and to hope that any other curve can be determined by its intersection numbers with reference curves. ...

WebNatural Topology. The natural topology in which to consider the approximation between states on the chain is the weak topology. From: Encyclopedia of … The term topology also refers to a specific mathematical idea central to the area of mathematics called topology. Informally, a topology describes how elements of a set relate spatially to each other. The same set can have different topologies. For instance, the real line, the complex plane, and the Cantor set can be thought of as the same set with different topologies. In any domain of mathematics, a space has a natural topology if there is a topology on the space which is "best adapted" to its study within the domain in question. In many cases this imprecise definition means little more than the assertion that the topology in question arises naturally or canonically (see mathematical jargon) in the given context. dave ramsey rental property advice
