Componentwise localization of critical points for functionals defined on product spaces
AbstractA new notion of linking is introduced to treat minima as minimax points in a unitary way. Critical points are…
Analysis of the effectiveness of the treatment of solid tumors in two cases of drug administration
AbstractA complete stability analysis of the equilibrium solutions of a system modeling tumor chemotherapy is performed in two cases of…
Stationary solutions of Fokker-Planck equations with nonlinear reaction terms in bounded domains
AbstractUsing an operator approach, we discuss stationary solutions to Fokker-Planck equations and systems with nonlinear reaction terms. The existence of…
Krasnoselskii type theorems in product Banach spaces and applications to systems of nonlinear transport equations and mixed fractional differential equations
AbstractIn this paper, we use a new technique for the treatment of systems based on the advantage of vector-valued norms…
Positive solutions for second-order differential equations of Kirchhoff type on the half-line
AbstractThe aim of the present paper is to study the existence of nontrivial nonnegative solutions for asecond-order boundary value problem…
A unified variational approach to discontinuous differential equations
AbstractA direct variational technique involving Clarke generalized gradient is used to treat general boundary value problems with discontinuous nonlinearities. Based…
Energy-based localization and multiplicity of radially symmetric states for the stationary p-Laplace diffusion
AbstractIt is investigated the role of the state–dependent source–term for the localization by means of the kinetic energy of radially…
Positive solutions for discontinuous systems via a multivalued vector version of Krasnosel’skii’s fixed point theorem in cones
AbstractWe establish the existence of positive solutions for systems of second–order differential equations with discontinuous nonlinear terms. To this aim,…
