CENTER PROBLEM FOR THIRD-ORDER ODEs [PDF]
International Journal of Bifurcation and Chaos, 2013 We obtain necessary and sufficient conditions for the existence of a center on a local center manifold for three 4-parameter families of quadratic systems on ℝ3. We also give a positive answer to an open question posed in [Dias & Mello, 2010] related to similar systems.

Oscillation Conditions for Third-Order Delay Differential Equations with Neutral-Type Term
MathematicsIn this work, we adopted an approach similar to that of Chatzarakis’, by transforming the oscillation analysis of third-order differential equations into an equivalent first-order problem.

Third order matching is decidable
Annals of Pure and Applied Logic, 1994 The higher order matching problem is the problem of determining whether a term is an instance of another in the simply typed $λ$-calculus, i.e. to solve the equation a = b where a and b are simply typed $λ$-terms and b is ground. The decidability of this problem is still open.

Fučı́k Spectrum for a Third Order Equation
Journal of Differential Equations, 1996 The Fučík spectrum of the third order boundary value problem \[ y''' + \mu y^+ - \nu y^- = 0,\;y(0) = y'(0) = y(1) = 0 \tag{1} \] is investigated, i.e. the set of all \((\mu, \nu) \in \mathbb{R}^2\) where (1) has a nontrivial solution \(y\). The eigenvalues of (1) are the numbers \(\lambda\) for which \((\lambda, \lambda)\) belongs to the Fučík ...

Improved Hille Oscillation Criteria for Nonlinear Functional Dynamic Equations of Third-Order
Mathematics, 2022 This paper aims to improve Hille oscillation criteria for the third-order functional dynamic equation p2(ξ)ϕγ2p1ξϕγ1yΔ(ξ)ΔΔ+a(ξ)ϕγy(g(ξ))=0, on an above-unbounded time scale T. The obtained results improve related contributions reported in the literature

Oscillation criteria for third-order functional half-linear dynamic equations
Advances in Difference Equations, 2017 In this paper, we study the third-order functional dynamic equation { r 2 ( t ) ϕ α 2 ( [ r 1 ( t ) ϕ α 1 ( x Δ ( t ) ) ] Δ ) } Δ + q ( t ) ϕ α ( x ( g ( t ) ) ) = 0 , $$ \bigl\{ r_{2}(t)\phi_{\alpha_{2}} \bigl( \bigl[ r_{1}(t) \phi _{\alpha _{1}} \bigl(

ON A THIRD ORDER DIFFERENCE EQUATION
Acta Universitatis Apulensis, 2018 Summary: In this paper, the authors solve the difference equation \[ x_{n+1} =\frac{x_nx_{n-2}}{-ax_n + bx_{n-2}}, \quad n = 0, 1, \dots, \] where \(a\) and \(b\) are positive real numbers and the initial values \(x_{-2}, x_{-1}\) and \(x_0\) are real numbers.
