Homogeneity argument
WebIf‖x‖ 1 >0, we can use a so-called homogeneity argument. Let λ=‖x‖ 1. Consider the vectory=λ− 1 x. Then by the properties of a norm we obtain‖y‖ 1 =λ− 1 ... However, this is a bit complicated as it requires a diagonal argument which can be confusing the first time you see it. We use the notation from introduced on the ... In physics, a homogeneous material or system has the same properties at every point; it is uniform without irregularities. A uniform electric field (which has the same strength and the same direction at each point) would be compatible with homogeneity (all points experience the same physics). A material constructed with different constituents can be described as effectively homogeneous in the electromagnetic materials domain, when interacting with a directed radiatio…
