Asymptotic behaviour at infinity of solutions of second kind integral equations on unbounded regions of Rn [PDF]
We consider second kind integral equations of the form x(s) - (abbreviated x - K x = y ), in which Ω is some unbounded subset of Rn. Let Xp denote the weighted space of functions x continuous on Ω and satisfying x (s) = O(|s|-p ),s → ∞We show that if the

Conjugacy and principal solution of generalized half-linear second order differential equations
We study the generalized half-linear second order differential equation and the associated Riccati type differential equation. We introduce the concepts of minimal and principal solutions of these equations and using these concepts we prove a new ...

Principal solution of half-linear differential equation: Limit and integral characterization
We investigate integral and limit characterizations of the principal solution of the nonoscillatory half-linear differential equation $$ (r(t)\Phi(x'))'+c(t)\Phi(x)=0,\quad \Phi(x)=|x|^{p-2},\ p>1 $$.

Modified Riccati technique for half-linear differential equations with delay
We study the half-linear differential equation $$ (r(t)\Phi(x'(t)))'+c(t)\Phi(x(\tau(t)))=0,\quad \Phi(x):=|x|^{p-2}x,\ p>1. $$ We formulate new oscillation criteria for this equation by comparing it with a certain ordinary linear or half-linear ...

On the integral characterization of principal solutions for half-linear ODE
We discuss a new integral characterization of principal solutions for half-linear differential equations, introduced in the recent paper of S. Fisnarova and R. Marik, Nonlinear Anal. 74 (2011), 6427-6433.

Oscillation criteria for fourth order half-linear differential equations [PDF]
In this paper, the following fourth-order differential equation \[(|y^{\prime\prime}|^{\alpha}\operatorname{sgn}(y^{\prime\prime}))^{\prime\prime}+q(t)|y|^{\alpha}\operatorname{sgn}(y)=0,\quad t\geq a>0\] is considered, where \(\alpha\) is a positive constant and \(q:[a,\infty)\to(0,\infty)\) is a continuous function.

On conjugacy of second-order half-linear differential equations on the real axis
Some conjugacy criteria are given for the equation $$ \big(|u'|^{\alpha}\operatorname{sgn}u'\big)'+p(t)|u|^{\alpha}\operatorname{sgn} u=0, $$ where $p\colon\mathbb{R} \to \mathbb{R}$ is a locally integrable function and $\alpha>0$, which generalise and ...
