Existence, localization and multiplicity results for positive radial solutions of semilinear elliptic systems
AbstractExistence, localization and multiplicity results of positive solutions to a system of singular second-order differential equations are established by means…
The role of matrices that are convergent to zero in the study of semilinear operator systems
AbstractIn this paper we explain the advantage of vector-valued norms and the role of matrices that are convergent to zero…
Existence results for semilinear elliptic boundary value problems via topological methods
Abstract In this work, existence and localization results for \(C_1\)-solutions to elliptic Dirichlet boundary value problems are established. The approach…

Two‐dimension potentials which generate spatial families of orbits
Abstract We consider the following case of the 3D inverse problem of dynamics: Given a spatial two-parametric family of curves…
On the approximation of the global extremum of a semi-Lipschitz function
AbstractIn this paper one obtains a sequential procedure for determining the global extremum of a semi-Lipschitz real-valued function defined on…
Mixed convection flow near an axisymmetric stagnation point on a vertical cylinder
AbstractThe mixed convection flow near an axisymmetric stagnation point on a vertical cylinder is considered. The equations for the fluid…
Solving inverse problems via hemicontractive maps
AbstractWe prove a “collage” theorem for hemicontractive maps and we use it for inverse problems. A numerical example is given.…
