This paper is devoted to the study the boundary value problem We prove the existence of at
least one, two or three solutions in the presence of a pair of, not necessarily ordered, lower …

The topic of singular boundary value problems has been of substantial and rapidly growing
interest for many scientists and engineers. This book is devoted to singular boundary value …

In this paper, we continue the study of the periodic problem for the second-order equation
[Formula: see text], where h is a Carathéodory function and f, g are continuous functions on …

We discuss existence, non-existence and multiplicity of positive solutions of the Dirichlet
problem for the one-dimensional prescribed curvature equation in connection with the …

In this text we investigate solvability of various nonlinear singular boundary value problems
for ordinary differential equations on the compact interval [0, T]. The nonlinearities in …

A periodic problem of Ambrosetti–Prodi type is studied in this paper for the Liénard equation
with a singularity of attractive type x ″+ f (x) x′+ φ (t) x m+ r (t) x μ= s, where f:(0,+∞)→ R is …

We consider the superlinear boundary value problem uʺ+ aμ (t) uγ+ 1= 0, u (0)= 0, u (1)= 0,
where γ> 0 and aμ (t) is a sign indefinite weight of the form a+ (t)− μa−(t). We prove, for μ …

Some generalized contractions using altering distances in partially ordered metric spaces
are investigated and their applications to fuzzy partial differential equations are considered …

We consider the singular boundary value problem (t^ n u't))'+ t^ nf (t, u (t))= 0,\lim t → 0+ t^ n
u'(t)= 0, a_0 u (1)+ a_1 u'(1-)= A, where f (t, x) is a given continuous function defined on the …
