The best known examples include those at the henge monument at Avebury, the Rollright Stones, Castlerigg, and elements within the ring of standing stones at Stonehenge. [1] Scattered examples exist from other parts of Europe. Later, during the Iron Age, stone circles were built in southern Scandinavia.
For example, the wide implementation of suburban railway networks and motor buses were expected to have proportionately impact the higher increases in periphery land prices. Contrastingly, it is expected that in periods of low innovation within the transport sector land values would have been proportionately higher closer to the city centre. [ 13 ]
A spectral map f: X → Y between spectral spaces X and Y is a continuous map such that the preimage of every open and compact subset of Y under f is again compact. The category of spectral spaces, which has spectral maps as morphisms, is dually equivalent to the category of bounded distributive lattices (together with homomorphisms of such ...
A ringed space (,) is a topological space together with a sheaf of rings on .The sheaf is called the structure sheaf of .. A locally ringed space is a ringed space (,) such that all stalks of are local rings (i.e. they have unique maximal ideals).
A figure-ground diagram is a two-dimensional map of an urban space that shows the relationship between built and unbuilt space. It is used in analysis of urban design and planning . It is akin to but not the same as a Nolli map which denotes public space both within and outside buildings and also akin to a block pattern diagram that records ...
A right primitive ring is defined similarly with right R-modules. There are rings which are primitive on one side but not on the other. The first example was constructed by George M. Bergman in (Bergman 1964). Another example found by Jategaonkar showing the distinction can be found in Rowen (1988, p. 159).

Some of the most important examples are topological fields. A topological field is a topological ring that is also a field, and such that inversion of non zero elements is a continuous function. The most common examples are the complex numbers and all its subfields, and the valued fields, which include the -adic fields.
