In this work, we are concerned with the existence of multiple positive fixed points for the sum
of an expansive mapping with constant h> 1 and ak‐set contraction when 0≤ k< h− 1. In …

The authors use fixed point index properties to prove existence of positive solutions to the
abstract Hammerstein equation u=LFu where L:E→E is a compact linear operator, F:K→K is …

In this paper, we discuss the existence of multiplicity of positive solutions to a new
generalized Riemann–Liouville type fractional Fisher‐like equation on a semi‐infinite …

In this work, we are concerned with the existence of positive solutions for a φ Laplacian
boundary value problem on the half-line. The results are proved using the fixed point index …

This work is devoted to the existence of positive, vanishing nontrivial solutions for singular
boundary value problems on the half-line. The nonlinearity, which encompasses some …

In this paper, we present an efficient numerical algorithm to solve the three‐point boundary
value problem on the half‐line based on the reproducing kernel theorem. Considering the …

In this work, we are concerned with the existence and multiplicity of positive solutions for
singular boundary value problems on the half-line. Two problems from epi-demiology and …

We establish not only sufficient but also necessary conditions for existence of solutions to a
singular multi-point third-order boundary value problem posed on the half-line. Our …
