On the number of limit cycles in generalized abel equations [PDF]

open access: yes, 2020
Given p, q ∊ Z ≥ 2 with p ≠ q, we study generalized Abel differential equations (Equation presented), where A and B are trigonometric polynomials of degrees n, m ≥ 1, respectively, and we are interested in the number of limit cycles (i.e., isolated ...

Uniform bounds on the 1-norm of the inverse of lower triangular Toeplitz matrices

open access: yes, 2011
A uniform bound on the 1-norm is given for the inverse of a lower triangular Toeplitz matrix with non-negative monotonically decreasing entries whose limit is zero. The new bound is sharp under certain specified constraints.

The composition conjecture for Abel equation

open access: yes, 2009
The composition conjecture for the Abel differential equation states that if all solutions in a neighborhood of the origin are periodic then the indefinite integrals of its coefficients are compositions of a periodic function.

U(1)-invariant membranes: The geometric formulation, Abel, and pendulum differential equations

open access: yes, 2010
The geometric approach to study the dynamics of U(1)-invariant membranes is developed. The approach reveals an important role of the Abel nonlinear differential equation of the first type with variable coefficients depending on time and one of the ...
