متن کاملOn Landau’s type inequalities for infinitesimal generators∗
We consider Landau’s type inequalities of the form ‖Aku‖n ≤ Cn,k‖u‖n−k‖Anu‖k, u ∈ D(A), 0 < k < n, where A is the infinitesimal generator of either a strongly continuous semigroup or a strongly continuous cosine function of linear contractions on a Banach space X. The constants Cn,k are computed for n ≤ 6.
متن کاملFurther Remarks on First-order Infinitesimal Mechanisms
This paper analyses a particular structural assembly that has two independent inextensional mechanisms and two independent states of self-stress. It is shown that, for certain values of a variable bar length, this assembly is a first-order infinitesimal mechanism; and yet it cannot be stiffened by the imposition of a state of prestress.
متن کاملSome Remarks on the Cross Correlation Analysis of Pseudo Random Generators
Siegenthaler has shown how cross-correlation techniques can be applied to identify pseudo random generators consisting of linear feedback shift registers and a scrambling function 171. These techniques may allow to attack one register in such a generator at a time. The original algorithm needs O(R2'N) operations to identify one register. ( r denotes the length of the register examined, R the nu...
متن کاملSome Remarks on Commuting Fixed Point Free Automorphisms of Groups
In this article we will find necessary and sufficient conditions for a fixed point free automorphism (fpf automorphism) of a group to be a commuting automorphism. For a given prime we find the smallest order of a non abelian p-group admitting a commuting f...
