چکیده
j=1 aijgj(uj(t)) + Ii (i = 1, · · · , n) (1, 1) where gj(x) are activation functions, di, aij are constants and Ii are constant inputs. In practice, however, the interconnections contain asynchronous terms in general, and the interconnection weights aij, bij , self-inhibition di and inputs Ii should depend on time, often periodically. Therefore, we need to discuss the following dynamical systems with time-varying delays dui dt = −di(t)ui(t) + n

متن کاملO ct 2 00 4 Dynamical systems method ( DSM ) for nonlinear equations in Banach spaces
Let F : X → X be a C 2 loc map in a Banach space X, and A be its Frèchet derivative at the element w := w ε , which solves the problem (*) ˙ w = −A −1 ε (F (w) + εw), w(0) = w 0 , where A ε := A + εI. Assume that A −1 ε ≤ cε −k , 0 < k ≤ 1, 0 < ε > ε 0. Then (*) has a unique global solution, w(t), there exists w(∞), and (* *) F (w(∞)) + εw(∞) = 0. Thus the DSM (Dynamical Systems Method) is just...

We consider the rational potentials of the one-dimensional mechanical systems, which have a family of periodic solutions with the same period (isochronous potentials). We prove that up to a shift and adding a constant all such potentials have the form U (x) = 1 2 ω 2 x 2 or U (x) = 1 8 ω 2 x 2 + c 2 x −2 .

The main result of this paper is the evidence of an explicit linearization of dynamical systems of Ruijsenaars-Schneider (RS) type and of the perturbations introduced by F. Calogero of these systems with all orbits periodic of same period. Several other systems share the existence of this explicit lineariza-tion, among them, the Calogero-Moser system (with and without external potential) and th...

We present numerical results on the static quark–anti-quark grand canonical potential in full QCD at non-vanishing temperature (T) and quark chemical potential (µ). Non-zero µ-s are reached by means of multi-parameter reweighting. The dynamical staggered simulations were carried out for n f = 2 + 1 flavors with physical quark masses on 4 × 12 3 lattices.
