1. Limit-Point/Limit-Circle Results for Superlinear Damped Equations

Author

M. Bartušek and John R. Graef

Subjects
Mathematics, QA1-939
Abstract

The authors study the nonlinear limit-point and limit-circle properties for second-order nonlinear damped differential equations of the form (a(t)|y'|p-1y')'+b(t)|y'|q-1y'+r(t)|y|λ-1y=0, where 00, and r(t)>0. Examples to illustrate the main results are included.

2. Fourth-Order Differential Equation with Deviating Argument

Author

M. Bartušek, M. Cecchi, Z. Došlá, and M. Marini

Subjects
Mathematics, QA1-939
Abstract

We consider the fourth-order differential equation with middle-term and deviating argument x(4)(t)+q(t)x(2)(t)+r(t)f(x(φ(t)))=0, in case when the corresponding second-order equation h″+q(t)h=0 is oscillatory. Necessary and sufficient conditions for the existence of bounded and unbounded asymptotically linear solutions are given. The roles of the deviating argument and the nonlinearity are explained, too.

4. On L2and limit-point type solutions of fourth order differential equations

Abstract

We study differential expressions of the fourth order and find sutficient conditions to ensure that they are not of the limit-circle type. In particular, we show that the differential expression y(4) + ry is never of the limit-circle type as long as r is not an unbounded oscillatory function; this partially answers an open question. Some of the results are deduced as consequences of new results on the nonlinear limit-point/limit-circle problem.

5. Global monotonicity and oscillation for second order differential equation.

Author

M. Bartušek, M. Cecchi, Z. Došlá, and M. Marini

Abstract

Abstract Oscillatory properties of the second order nonlinear equation $$\left( {r\left( t \right)x'} \right)^\prime + q\left( t \right)f\left( x \right) = 0$$ are investigated. In particular, criteria for the existence of at least one oscillatory solution and for the global monotonicity properties of nonoscillatory solutions are established. The possible coexistence of oscillatory and nonoscillatory solutions is studied too. [ABSTRACT FROM AUTHOR]

Abstract

The complex equilibria of the uranyl ion with a number of mono, di- and trihydric phenols and 3-hydroxy-4-pyrones were studied and the stability constants calculated. Some general conclusions on the stability, structures and optical properties of particular complexes were given and their significance for sensitive spectrophotometric determination of UO22+ in aqueous solution was outlined.
