On the critical periods of Liénard systems with cubic restoring forces
We study local bifurcations of critical periods in the neighborhood of a nondegenerate center of a Liénard system of the form ẋ = −y + F(x), ẏ = g(x), where F(x) and g(x) are polynomials such that deg(g(x)) ≤ 3, g(0) = 0, and g′(0) = 1, F(0) = F ′(0) = 0 and the system always has a center at (0,0). The set of coefficients of F(x) and g(x) is split into two strata denoted by SI and SII and (0,0)...
متن کاملHopf bifurcations on cubic lattices
Group theoretic means are employed to analyse the Hopf bifurcation on pattern forming systems with the periodicity of the face-centred (FCC) and bodycentred (BCC) cubic lattices. We find all C-axial subgroups of the normal form symmetry group by first extending the symmetry to a larger group. There are 15 such solutions for the FCC lattice, of which at least 12 can be stable for appropriate par...
متن کاملApproximately cubic functional equations and cubic multipliers
* Correspondence: abasalt. [email protected] Department of Mathematics, Garmsar Branch, Islamic Azad University, Garmsar, Iran Full list of author information is available at the end of the article Abstract In this paper, we prove the Hyers-Ulam stability and the superstability for cubic functional equation by using the fixed point alternative theorem. As a consequence, we show that the cubic m...
متن کاملPurely Cubic Function Fields With Short Periods
A “function field version” of Voronoi’s algorithm can be used to compute the fundamental unit of a purely cubic complex congruence function field of characteristic at least 5. This is accomplished by generating a sequence of minima in the maximal order of the field. The number of mimima computed is the period of the field. Generally, the period is very large — it is proportional to the regulato...
متن کاملGlobal Well-posedness for Cubic Nls with Nonlinear Damping
u(0) = u0(x), with given parameters λ ∈ R and σ > 0, the latter describing the strength of the dissipation within our model. We shall consider the physically relevant situation of d 6 3 spatial dimensions and assume that the dissipative nonlinearity is at least of the same order as the cubic one, i.e. p > 3. However, in dimension d = 3, we shall restrict ourselves to 3 6 p 6 5. In other words, ...
