Positive solutions for the (n, p) boundary value problem
, 2015 We consider the (n, p) boundary value problem in this paper. Some new upper estimates to positive solutions for the problem are obtained. Existence and nonexistence results for positive solutions of the problem are obtained by using the Krasnosel’skii ...

Demonstratio MathematicaOwing to the non-ideal properties of the Green’s function associated with the boundary value problem of Caputo-Hadamard fractional differential equations, a complete theoretical framework for studying such solutions has remained elusive.

On singularly weighted generalized Laplacian systems and their applications
Advances in Nonlinear Analysis, 2018 We study the homogeneous Dirichlet boundary value problem of generalized Laplacian systems with a singular weight which may not be integrable. Some explicit intervals which correspond to the existence and nonexistence of positive solutions for the system

One-dimensional singular problems involving the p-Laplacian and nonlinearities indefinite in sign
Advances in Nonlinear Analysis, 2016 Let Ω be a bounded open interval, let p>1${p>1}$ and γ>0${\gamma>0}$, and let m:Ω→ℝ${m:\Omega\rightarrow\mathbb{R}}$ be a function that may change sign in Ω.
