For a magma chamber to form, the right conditions have to exist, including particular temperatures, pressures, and structural formations. Magma chambers are under such great pressure that, over time, they can eventually break the rock surrounding the chamber.
A vector space on which a norm is defined is then called a normed vector space. Normed vector spaces are central to the study of linear algebra and functional analysis.imilarly, for any semi-normed vector space we can define the distance between two vectors u and v as â u â v â. This turns the seminormed space into a pseudometric space (notice this is weaker than a metric) and allows the definition of notions such as continuity and convergence.
O'Meara [24] generalized the concept of âµ0âµ0-spaces as follows: A topological space X is called an âµ-space if it is regular and has a Ï-locally finite k-network. Any metrizable space is an âµ-space and all compact sets in âµ-spaces are metrizable. For further results, see [15]. The study of those locally convex spaces E which are weakly âµ-spaces (i.e. under the weak topology E has a Ï-locally finite k-network) is begun here for the important particular case of FrÃ©chet lcs.
