In this paper we prove the existence and the uniqueness of classical solution of non-autonomous inhomogeneous boundary Cauchy problems, this solution is given by a variation
Key words: radially symmetric solution, nonlinear elliptic partial differential equa- tions, uniqueness, monotone dependence on the boundary value,
Then we have the following fixed point theorem, given in Boyd and Wong [1], which is useful for proving the existence and uniqueness theorems for nonlinear differential and
The following fixed point theorem for the nonlinear contraction is well-known and useful for proving the existence and the uniqueness theorems for the nonlinear differ- ential
Abstract: In this paper, we study the existence of positive solutions for a nonlinear four- point boundary value problem with a p -Laplacian operator. By using a three functionals
In this paper, we consider a two-point boundary value problem involving fractional semilinear evolution equations and prove some existence results in a Banach space...

In this paper, we prove the existence of solutions for an anti-periodic boundary value problem of nonlinear impulsive fractional differential equations by applying some known
