Nonoscillation and disconjugacy of systems of linear differential equations
The differential equations under consideration are of the form (1) §f = A(t)x, where A(t) is a piecewise continuous real nxn-matrix on a real interval a, and the vector x = (x-j...,x ) is continuous on a. The equation is said to be nonoscillatory on a if every nontrivial real solution vector x has at least one component xv which does not vanish on a. The principal concern of this paper is the d...
متن کاملSeparation and Disconjugacy
We show that certain properties of positive solutions of disconjugate second order differential expressions M [y] = −(py) + qy imply the separation of the minimal and maximal operators determined by M in L 2 (I a) where I a = [a, ∞), a > −∞, i.e., the property that M [y] ∈ L 2 (I a) ⇒ qy ∈ L 2 (I a). This result will allow the development of several new sufficient conditions for separation and ...
متن کاملDisconjugacy and the Secant Conjecture
We discuss the so-called secant conjecture in real algebraic geometry, and show that it follows from another interesting conjecture, about disconjugacy of vector spaces of real polynomials in one variable. AMS Class 2010: 14P99, 34C10, 26C10.
متن کاملEventual Consistency
In a replicated database, the consistency level defines whether and how the values of the replicas of a logical object may diverge in the presence of updates. Eventual consistency is the weakest consistency level that guarantees convergence. Informally, it requires that all replicas of an object will eventually reach the same, correct, final value, assuming that no new updates are submitted to ...
متن کاملHorizontal saccade disconjugacy in strabismic monkeys.
PURPOSE Previous studies have shown that binocular coordination during saccadic eye movement is affected in humans with large strabismus. The purpose of this study was to examine the conjugacy of saccadic eye movements in monkeys with sensory strabismus. METHODS The authors recorded binocular eye movements in four strabismic monkeys and one unaffected monkey. Strabismus was induced by first o...
