A system of nonlinear ordinary differential equations allowing a superposition formula can be associated with every Lie groupâ€“subgroup pair G[contains]G0. We consider the case when G=SL(n+k,C) and G0=P(k) is a maximal parabolic subgroup of G, leaving a k-dimensional vector space invariant...

We study the positive solutions of equation ï¿½, via the Riccati technique and prove an integral sufficient condition on the potential function c(x) and the damping b?(x) which ensures that no positive solution of the equation satisfies a lower (if p > q) or upper (if q > p) bound eventually.

By means of generalized Riccati transformation techniques and generalized exponential functions, some oscillation criteria are given for the nonlinear dynamic equation \[ (p(t)x^{\Delta} (t))^{\Delta}+q(t)(f\circ x^{\sigma})=0 \] on time scales. The results are also applied to linear and...
