چکیده
We study the number of limit cycles of T−periodic Chini equations and some generalized Abel equations and apply the results obtained to illustrate the existence of isochronous centers in three-dimensional autonomous differential systems.

Characterization of isochronous foci for planar analytic differential systems
We consider the two-dimensional autonomous systems of differential equations of the form: ẋ = λx− y + P (x, y) , ẏ = x + λy + Q(x, y) , where P (x, y) and Q(x, y) are analytic functions of order ≥ 2. These systems have a focus at the origin if λ 6= 0, and have either a center or a weak focus if λ = 0. In this work we study necessary and sufficient conditions for the existence of an isochronous ...
متن کاملON MAXWELL'S STRESS FUNCTIONS FOR SOLVING THREE DIMENSIONAL ELASTICITY PROBLEMS IN THE THEORY OF ELASTICITY
The governing equations of three dimensional elasticity problems include the six Beltrami-Michell stress compatibility equations, the three differential equations of equilibrium, and the six material constitutive relations; and these are usually solved subject to the boundary conditions. The system of fifteen differential equations is usually difficult to solve, and simplified methods are usual...

متن کاملSymmetry group, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation
In this paper Lie point symmetries, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation are investigated. First of all Lie symmetries are obtained by using the general method based on invariance condition of a system of differential equations under a prolonged vector field. Then the structure of symmetry ...
