Typical risk measures are law-invariant: the expectation, the average value-at-risk, the mean upper semi-deviations, the … Web(convex) law-invariant risk measure collapses to the mean, i.e., being a scalar multiple of expectation. We are motivated to study the problem for linear functionals. Precisely, we …

Webtributions. We show that, given a law-invariant convex risk measure, on the level of distributions, if at all, concavity holds true. In particular, this is always the case under the additional assumption of comonotonicity. Keywords: convexity, law-invariant risk measure, convex order, comonotonicity MSC 2010 Classi cation: 46N10, 60E15, 91B30 Web12 sep. 2024 · The distance Δr is invariant under a rotation of axes. If a new set of Cartesian axes rotated around the origin relative to the original axes are used, each point in space will have new coordinates in terms of the new axes, but the distance Δr ′ given by Δr ′ 2 = (Δx ′)2 + (Δy ′)2 + (Δz ′)2. That has the same value that Δr2 had.

Webis said to be scale invariant. The most general function f ( x) that satisfies the previous condition is of the form f ( x) = C x Δ If we consider the set of distributions, namely the set of all f ( x) such that ∫ f ( x) d x = 1, is it possible to prove that the only distribution that is invariant under scale transformation is f ( x) = C x − 1. Web17 sep. 2024 · Newton's second law is covariant as it is a vector law that doesn't change its configuration when switching reference frames. This needs to be stated very carefully. 3-vector laws are not necessarily even covariant. 4-vector laws are, but Newton's second law in its usual form can't be written as a 4-vector law in the general case.

WebKusuoka (2001) has obtained explicit representation theorems for comonotone risk measures and, more generally, for law invariant risk measures. These theorems pertain, like most of the previous literature, to the case of scalar-valued risks. Jouini, Meddeb, and Touzi (2004) and Burgert and Rüschendorf (2006) extended the notion of risk measures …
WebInvariant intervals and the Light Cone Points in spacetime are more precisely thought of as events. By construction Lorentz transformations leave the quantity x· x= x2 − c2t2 invariant. But since all events are subject to the same transformation, the “interval” between two events s2 12 = (x1 −x2)·(x1 −x2) is also invariant. ti clog\u0027sWeb13 apr. 2024 · We consider a generalized nonlocal Ginzburg–Landau equation with periodic boundary conditions.
