Principal solution of half-linear differential equation: Limit and integral characterization

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2008
We investigate integral and limit characterizations of the principal solution of the nonoscillatory half-linear differential equation $$ (r(t)\Phi(x'))'+c(t)\Phi(x)=0,\quad \Phi(x)=|x|^{p-2},\ p>1 $$.

Exact Solution Analysis of Strongly Convex Programming for Principal Component Pursuit

open access: yesInformation, 2017
In this paper, we address strongly convex programming for principal component analysis, which recovers a target matrix that is a superposition of low-complexity structures from a small set of linear measurements.

A Twisting Electrovac Solution of Type II with the Cosmological Constant [PDF]

open access: yes, 2000
An exact solution of the current-free Einstein-Maxwell equations with the cosmological constant is presented. It is of Petrov type II, and its double principal null vector is geodesic, shear-free, expanding, and twisting.

Families of Principal Solutions of Ordinary Differential Equations [PDF]

open access: yesTransactions of the American Mathematical Society, 1963
Let A(y, Dy, ..., D'y) = 0 be an algebraic differential equation belonging to Strodt's class (D) [1, p. 5], and let M be a principal monomial [1, ?66] for A = 0. In search for principal solutions of A = 0 (i.e., solutions which are M) one substitutes y = M(1 + z).

Remarks on the Schrödinger-Lohe model

open access: yesNetworks and Heterogeneous Media, 2019
We study the Schrödinger-Lohe model. Making use of the principal fundamental matrix \begin{document}$ Y $\end{document} of linear ODEs with variable coefficients, the coupled nonlinear Schrödinger-Lohe system is transformed into the decoupled linear ...

Singular measure as principal eigenfunction of some nonlocal operators

open access: yes, 2013
In this paper, we are interested in the spectral properties of the generalised principal eigenvalue of some nonlocal operator. That is, we look for the existence of some particular solution $(\lambda,\phi)$ of a nonlocal operator. $$\int_{\O}K(x,y)\phi(y)
