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 normed vector space is a pair (V, âÂ·â) where V is a vector space and âÂ·â a norm on V.A seminormed vector space is a pair (V, p) where V is a vector space and p a seminorm on V.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.
Vector. A vector is formally defined as an element of a vector space. In the commonly encountered vector space (i.e., Euclidean n-space), a vector is given by coordinates and can be specified as . Vectors are sometimes referred to by the number of coordinates they have, so a 2-dimensional vector is often called a two-vector, an -dimensional vector is often called an n-vector, and so on.
