A mathematical model of the transition from the normal hematopoiesis to the chronic and acceleration-acute stages in myeloid leukemia
AbstractA mathematical model given by a two-dimensional differential system is introduced in order to understand the transition process from the…
On the approximation of fixed points for non-self mappings on metric spaces
AbstractStarting from some classical results of R. Conti, A. Haimovici and K. Iseki, and from a more recent result of…
Positive periodic solutions for Lotka-Volterra systems with a general attack rate
AbstractThe paper deals with a non-autonomous Lotka–Volterra type system, which in particular may include logistic growth of the prey population and…
Localization and multiplicity in the homogenization of nonlinear problems
AbstractWe propose a method for the localization of solutions for a class of nonlinear problems arising in the homogenization theory.…
Assessment of measurable residual disease in chronic myeloid leukemia. BCR-ABL1 IS in the avant-garde of molecular hematology
AbstractChronic myelogenous leukemia (CML) is a malignancy of the myeloid cell lineage characterized by a recurrent chromosomal abnormality: the Philadelphia…
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,…
A four-point boundary value problem with singular φ-Laplacian
Abstract We prove that the four-point boundary value problem \(-[\U{3d5} (u\prime)]\prime=f(t,u,u\prime),u(0)=\U{3b1} u(\U{3be}),u(T)=\U{3b2} u(\U{3b7} ),)\ where \(f:[0,T]\times R^{2}\rightarrow R)\ is continuous,…
Existence results for some neutral functional integrodifferential equations with bounded delay
Abstract In this paper, we study a class of neutral functional integrodifferential equations with finite delay in Banach spaces. We…
Positive solutions for φ-Laplace equations with discontinuous state-dependent forcing terms
AbstractThis paper concerns the existence, localization and multiplicity of positive solutions for a φ-Laplacian problem with a perturbed term that…
