Existence and multiplicity of periodic solutions generated by impulses
and Applied Analysis 3 Remark 1.3. It is easy to see that V ′ 1 , V ′ 2 are weaker than V1 , V2 . Therefore, Theorem 1.2 improves Theorem A. Indeed, taking V t, u −|u| − |u|, 1 < γ < ς ≤ 2, Gk u −|u|, 1.3 all conditions in Theorem 1.4 are satisfied, but conditions in Theorem A cannot be satisfied. Theorem 1.4. Assume that V1 , V2 hold. Moreover, the following conditions are satisfied: V3 Vu t, ...
متن کاملCircuit Generated by Terms and Circuit Calculating Terms
In the paper we investigate the dependence between the structure of circuits and sets of terms. Circuits in our terminology (see [19]) are treated as locally-finite many sorted algebras over special signatures. Such approach enables to formalize every real circuit. The goal of this investigation is to specify circuits by terms and, enentualy, to have methods of formal verification of real circu...
متن کاملMultiple solutions for a degenerate elliptic equation involving sublinear terms at infinity
Some multiplicity results are presented for the eigenvalue problem { −div(|x|−2a∇u)= λ|x|−2bf (u)+μ|x|−2cg(u) in Ω, u= 0 on ∂Ω, (Pλ,μ) where Ω ⊂Rn (n 3) is an open bounded domain with smooth boundary, 0 ∈Ω , 0 < a < n−2 2 , a b, c < a + 1, and f :R→R is sublinear at infinity and superlinear at the origin. Various cases are treated depending on the behaviour of the nonlinear term g. © 2008 Elsev...
متن کاملEntire Solutions for a Quasilinear Problem in the Presence of Sublinear and Super-Linear Terms
We establish new results concerning existence and asymptotic behavior of entire, positive, and bounded solutions which converge to zero at infinite for the quasilinear equation −Δpu a x f u λb x g u , x ∈ R, 1 < p < N,where f, g : 0,∞ → 0,∞ are suitable functions and a x , b x ≥ 0 are not identically zero continuous functions. We show that there exists at least one solution for the above-mentio...
متن کاملMultiple Positive Periodic Solutions to a Periodic Predator-Prey-Chain Model with Harvesting Terms
In this paper, a class of predator-prey-chain model with harvesting terms are studied. By using Mawhin’s continuation theorem of coincidence degree theory and some skills of inequalities, some sufficient conditions are established for the existence of eight positive periodic solutions. Finally, an example is presented to illustrate the feasibility and effectiveness of the results. Keywords—Posi...
