Oscillatory results for second-order noncanonical delay differential equations [PDF]

open access: yesOpuscula Mathematica, 2019
The main purpose of this paper is to improve recent oscillation results for the second-order half-linear delay differential equation \[\left(r(t)\left(y'(t)\right)^\gamma\right)'+q(t)y^\gamma(\tau(t))= 0, \quad t\geq t_0,\] under the condition \[\int_ ...

Oscillatory behavior of second-order damped differential equations with a superlinear neutral term [PDF]

open access: yesOpuscula Mathematica, 2020
This article concerns the oscillatory behavior of solutions to second-order damped nonlinear differential equations with a superlinear neutral term. The results are obtained by a Riccati type transformation as well as by an integral criterion.

SECOND-ORDER INVARIANTS AND HOLOGRAPHY [PDF]

open access: yesInternational Journal of Modern Physics D, 2012
Motivated by recent works on the role of the holographic principle in cosmology, we relate a class of second-order Ricci invariants to the IR cutoff characterizing the holographic dark energy density. The choice of second-order invariants provides an invariant way to account the problem of causality for the correct cosmological cutoff, since the ...

Second-order Darboux displacements [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2003
The potentials for a one dimensional Schroedinger equation that are displaced along the x axis under second order Darboux transformations, called 2-SUSY invariant, are characterized in terms of a differential-difference equation. The solutions of the Schroedinger equation with such potentials are given analytically for any value of the energy.

Second-Order Finite Automata [PDF]

open access: yesTheory of Computing Systems, 2020
AbstractTraditionally, finite automata theory has been used as a framework for the representation of possibly infinite sets of strings. In this work, we introduce the notion of second-order finite automata, a formalism that combines finite automata with ordered decision diagrams, with the aim of representing possibly infinitesets of setsof strings. Our

Second-Order Sliding Mode Guidance Law considering Second-Order Dynamics of Autopilot

open access: yesJournal of Control Science and Engineering, 2019
Aiming at the requirement that some missiles need to meet certain impact angles when attacking targets, we consider the second-order dynamic characteristics of autopilot, thereby proposing a second-order sliding mode guidance law with impact angle ...

Second-Order Consistencies

open access: yesJournal of Artificial Intelligence Research, 2011
In this paper, we propose a comprehensive study of second-order consistencies (i.e., consistencies identifying inconsistent pairs of values) for constraint satisfaction. We build a full picture of the relationships existing between four basic second-order consistencies, namely path consistency (PC), 3-consistency (3C), dual consistency (DC) and 2 ...

Second-Order Democratic Aggregation [PDF]

open access: yes, 2018
Aggregated second-order features extracted from deep convolutional networks have been shown to be effective for texture generation, fine-grained recognition, material classification, and scene understanding. In this paper, we study a class of orderless aggregation functions designed to minimize interference or equalize contributions in the context of ...

Pure Second-Order Logic with Second-Order Identity

open access: yesNotre Dame Journal of Formal Logic, 2010
Pure second-order logic is second-order logic without functional or first-order variables. In "Pure Second-Order Logic," Denyer shows that pure second-order logic is compact and that its notion of logical truth is decidable. However, his argument does not extend to pure second-order logic with second-order identity.
