An important problem in a given dynamical system is to determine the existence of a homoclinic orbit. We improve the results of Qin and Xiao [Nonlinearity, 20 (2007), 2305-2317], who present some sufficient conditio...

We study the local analytic solutions f of the functional equation f(ψ(zf(z))) = φ(f(z)) for z in some neighborhood of the origin. Whether the solution f vanishes at z = 0 or not plays a critical role for ...
