Periodic solutions of Euler-Lagrange equations with sublinear potentials in an Orlicz-Sobolev space setting
Journal Title: Annales Universitatis Mariae Curie-Skłodowska. Sectio A, Mathematica - Year 2017, Vol 71, Issue 2
Abstract
In this paper, we obtain existence results of periodic solutions of hamiltonian systems in the Orlicz-Sobolev space W1LΦ([0,T]). We employ the direct method of calculus of variations and we consider a potential function F satisfying the inequality |∇F(t,x)|≤b1(t)Φ′0(|x|)+b2(t), with b1,b2∈L1 and certain N-functions Φ0.

On a two-parameter generalization of Jacobsthal numbers and its graph interpretation
In this paper we introduce a two-parameter generalization of the classical Jacobsthal numbers ((s, p)-Jacobsthal numbers). We present some properties of the presented sequence, among others Binet’s formula, Cassini’s ide...
An existence and approximation theorem for solutions of degenerate nonlinear elliptic equations
The main result establishes that a weak solution of degenerate nonlinear elliptic equations can be approximated by a sequence of solutions for non-degenerate nonlinear elliptic equations.
On generalized Mersenne numbers, their interpretations and matrix generators
In this paper we introduce generalized Mersenne numbers. We shall present some of their interpretations and matrix generators which are very useful for determining identities.
Entire functions of exponential type not vanishing in the half-plane Iz>k, where k>0
Let P(z) be a polynomial of degree n having no zeros in |z|<k, k≤1, and let Q(z):=znP(1/z). It was shown by Govil that if max|z|=1|P′(z)| and max|z|=1|Q′(z)| are attained at the same point of the unit circle |z|=1, then...
The Riemann-Cantor uniqueness theorem for unilateral trigonometric series via a special version of the Lusin-Privalov theorem
Using Baire's theorem, we give a very simple proof of a special version of the Lusin-Privalov theorem and deduce via Abel's theorem the Riemann-Cantor theorem on the uniqueness of the coefficients of pointwise converge...
