AND M ATZEU M., Existence and multiplicity results for periodic solutions of superquadratic Hamiltonian systems where the potential changes sign, Nonlinear Differential Equations
We want to find upper and lower bounds (or approximations, if bounds are not available) for the entries of a function of a matrix. We shall examine analytical expressions as well
According to the behavior of the nonlinear source term, existence re- sults of bounded solutions, positive solutions, classical as well as weak solutions are provided.. For other

Some existence criteria are established for a class of fourth-order m -point boundary value prob- lem by using the upper and lower solution method and the Leray-Schauder
The aim of this paper is to establish the existence of solutions and some prop- erties of set solutions for a Cauchy problem with causal operator in a separable Banach space..
Abstract In this paper, the M¨ onch fixed point theorem is used to investigate the existence of positive solutions for the second-order boundary value problem with integral
