We provide an accurate upper bound of the maximum number of limit cycles that this class of systems can have bifurcating from the periodic orbits of the linear center ˙ x = y, y ˙ =
We study a Neumann boundary-value problem on the half line for a second order equation, in which the nonlinearity depends on the (unknown) Dirichlet boundary data of the solution..
(The Elliott-Halberstam conjecture does allow one to take B = 2 in (1.39), and therefore leads to small improve- ments in Huxley’s results, which for r ≥ 2 are weaker than the result

Algebraic curvature tensor satisfying the condition of type (1.2) If ∇J ̸= 0, the anti-K¨ ahler condition (1.2) does not hold.. Yet, for any almost anti-Hermitian manifold there
In this paper, for each real number k greater than or equal to 3 we will construct a family of k-sum-free subsets (0, 1], each of which is the union of finitely many intervals
