Nonlocal Hadamard fractional integral conditions for nonlinear Riemann-Liouville fractional differential equations

, 2014
In this paper, we introduce a new class of boundary value problems consisting of a fractional differential equation of Riemann-Liouville type, DqRLx(t)=f(t,x(t)), t∈[0,T], subject to the Hadamard fractional integral conditions x(0)=0, x(T)=∑i=1nαiHIpix ...

Global structure of positive and sign-changing periodic solutions for the equations with Minkowski-curvature operator

Advanced Nonlinear Studies
We show the existence of unbounded connected components of 2π-periodic positive solutions for the equations with one-dimensional Minkowski-curvature operator −u′1−u′2′=λa(x)f(u,u′),x∈R, $-{\left(\frac{{u}^{\prime }}{\sqrt{1-{u}^{\prime 2}}}\right ...

Non-homogeneous BVPs for second-order symmetric Hamiltonian systems

Open Mathematics
By making use of Bolle’s method, we show that the following problem has infinitely many solutions: x¨+V′(x)=0,x(0)cosα−x˙(0)sinα=x0,x(1)cosβ−x˙(1)sinβ=x1,\begin{array}{rcl}\ddot{x}+{V}^{^{\prime} }\left(x)& =& 0,\\ x\left(0)\cos \alpha -\dot{x}\left(0 ...
