... classification, but just as a description of the phase portrait of the foliations around the singular point. One of the main ingredients of the classification is the index of an isolated singular point. It is defined as a rational number of the form k/n, where k ∈ Z and it can be interpreted as the ...

There turned out to be an unexpected difference between dimension d = 1 and higher dimensions, which presents us with ...

... of f is a subspace of W , and we write θ(f ) for the quotient space W/im(f ). Proposition 2.2 Let g : V → V and h : W → W be invertible linear transformations. Then θ(f ) is isomorphic to θ(hf g). It follows that if we have the matrix equation A(f � ) = A(h)A(f )A(g), then θ(f � ) is isomorphic to θ ...

Four-vector

In the theory of relativity, a four-vector or 4-vector is a vector in Minkowski space, a four-dimensional real vector space. It differs from a Euclidean vector in how its magnitude is determined. The transformations that preserve this magnitude are the Lorentz transformations, which include spatial rotations, boosts (a change by a constant velocity to another inertial reference frame), and temporal and spatial inversions. Regarded as a homogeneous space, the transformation group of Minkowski space is the Poincaré group, which adds to the Lorentz group the group of translations. The Lorentz group may be represented by 4×4 matrices.The article considers four-vectors in the context of special relativity. Although the concept of four-vectors also extends to general relativity, some of the results stated in this article require modification in general relativity.
