... I. Let f (x) = sin x. The sine function f (x) = sin x is neither strictly increasing nor strictly decreasing in its entire domain, and hence the sine function has no inverse in its entire domain. Now we need to choose an interval on which the sine function has an inverse on the restricted domain. To ...

HOW TO DEDUCE A PROPER EIGENVALUE CLUSTER FROM A

... situations occur when dealing with partial differential equations and structured matrices (see, e.g., [2, 7]); in particular, concerning the aforementioned applications, we stress that there exist many tools for proving the singular value clustering in the nonnormal case [8, 6, 7], but not so many fo ...

This is possible because translational and rotational components of the motion of a rigid body do not interact with one another.1 We have already studied a particularly simple form of rotati ...

Using a Chern character and applied to special operators coming from geometry, there is a very explicit cohomological formula for this index. ...

We will define a finite set of uniformly distributed divisors in Pic0F to help us compute with this group. First we take the canonical metric on I coming from OF and scale it uniformly so tha ...

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.
