Symmetric gauge function
WebA symmetric norm (also known as a symmetric gauge function) is a norm on IRn such that kPxk = kxk for all P ∈ GP(n) and all x ∈ IRn. Evidently, ‘ p norms and c-norms are symmetric norms. Suppose one focuses on the isometry group G of a symmetric norm. It is easy to see that G must be closed and bounded, i.e., WebAbstract: We consider the flow of a viscoelastic fluid in a symmetric cross geometry. For small driving pressures the flow is symmetric, but beyond a certain critical pressure the symmetric flow becomes unstable; two stable asymmetric solutions appear, and forcing of the unstable symmetric flow beyond the critical pressure gives rise to increased hydraulic …

WebTheorem 2.2 There is a one-one correspondence between symmetric gauge functions on Rn and UI norms on M n, namely, each UI norm k·k corresponds to a unique symmetric gauge unction Φ such that kAk = Φ(s(A)). (a) Every UI norm k·k there is a compact set E of nonnegative vectors with entries arranged in descending order such that kAk = max{kAk
