Struktur, Aufgabenstellung und Arbeitsweise,ity condition, magnitudes for vectors and “circles” looking like ellipses. This shows that a metric is non-unique for a given vector space and there is a need to consider vector spaces devoid of the metric.countenance 发表于 2025-3-25 16:53:06
Staat und technische Kommunikation.1. In each of the linear spaces, bases can be introduced and dimensions of the spaces determined. The coefficients of expanding a given quantity in the basis are called coordinates, not components, because the two notions can be ascribed to one vector and should be distinguished.极少 发表于 2025-3-25 21:41:58

Electromagnetism in Space-Time,imensional vector space. The transition from three-dimensional space to a plane described in a previous chapter is helpful to perform the passage in opposite direction, namely from three to four dimensions, in Sect. 7.2. A distinguished vector protruding in the fourth dimension is necessary for this
