DOI: 10.1007/s00205-018-01352-7
Abstract: AbstractIn this paper we study the existence and multiplicity of solutions of the Lorentz force equation $$\left(\frac{q'}{\sqrt{1-|q'|^2}}\right)'=E(t,q) + q'\times B(t,q)$$q′1-|q′|2′=E(t,q)+q′×B(t,q)with periodic or Dirichlet boundary conditions. In Special Relativity, this equation models the motion of a… read more here.

DOI: 10.1007/s10902-017-9888-4
Abstract: Can a society’s overall level of happiness change? Until recently, it was widely held that happiness fluctuates around set-points, so that neither individuals nor societies can lastingly increase their happiness. However, data from surveys carried… read more here.

DOI: 10.1017/s001309151600050x
Abstract: Abstract We consider a fractional equation involving the left and right Riemann–Liouville fractional integrals and with Sturm–Liouville boundary-value conditions. We establish the variational structure of the problem and, by using critical-point theory, the existence of… read more here.

DOI: 10.24193/fpt-ro.2018.1.11
Abstract: In this paper some estimates of M -constants in Orlicz-Lorentz sequence spaces for both, the Luxemburg and the Amemiya norms are given. Since degenerated Orlicz functions φ and degenerated weighted sequences ω are also admitted,… read more here.
