Asymptotic Theory for a General Third-Order Differential Equation of Euler Type

Euler case for a general fourth-order differential equation

as x →∞, where x is the independent variable and the prime denotes d/dx. The functions pi(x) (0 ≤ i ≤ 2) and qi(x) (i = 1,2) are defined on an interval [a,∞), are not necessarily real-valued, and are all nowhere zero in this interval. Our aims are to identify relations between q0, q1, p0, p1, and p2 that represents an Euler case for (1.1) and to obtain the asymptotic forms of four linearly inde...

Constructing a Third-Order Linear Differential Equation

In this paper, using the approach of Hurwitz and the necessary conditions given in 4,6], we construct a third order linear diierential equation whose diierential Galois group is the primitive subgroup F SL3 36 S L(3; C) of order 108.

New Results on the Asymptotic Behavior of a Third–order Nonlinear Differential Equation

Sufficient conditions are established for the asymptotic behavior of a third-order nonlinear differential equation. Our results improve on Qian’s [C. Qian, Asymptotic behavior of a third-order nonlinear differential equation, J. Math. Anal. Appl., 284 (2003), 191–205]

Mixed Problem with Nonlocal Boundary Conditions for a Third-order Partial Differential Equation of Mixed Type

We study a mixed problem with integral boundary conditions for a third-order partial differential equation of mixed type. We prove the existence and uniqueness of the solution. The proof is based on two-sided a priori estimates and on the density of the range of the operator generated by the considered problem. 2000 Mathematics Subject Classification. 35B45, 35K20, 35M10.
