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.
A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set. Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components.
