Implicit elliptic equations via Krasnoselskii-Schaefer type theorems

3 May at 10:11 am

AbstractExistence of solutions to the Dirichlet problem for implicit elliptic equations is established by using Krasnoselskii–Schaefer type theorems owed to…

Fixed point index theory for decomposable multivalued maps and applications to φ-Laplacian problems

3 May at 8:49 am

Abstract In this paper, we develop a fixed point index theory for decomposable multivalued maps, that is, compositions of two…

Harnack type inequalities and multiple solutions in cones of nonlinear problems

2 May at 8:49 am

AbstractThe paper presents an abstract theory regarding operator equations and systems in ordered Banach spaces. We obtain existence, localization and…

Integrodifferential evolution systems with nonlocal initial conditions

2 May at 7:16 am

AbstractThe paper deals with systems of abstract integrodifferential equations subject to general nonlocal initial conditions. In order to allow the…

A mathematical model of the transition from the normal hematopoiesis to the chronic and acceleration-acute stages in myeloid leukemia

2 May at 6:57 am
