Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks
Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

Ground state solutions and asymptotics for discrete Kirchhoff problems
Electronic Journal of Differential EquationsWhile superlinear discrete Kirchhoff problems have been extensively studied via variational minimax methods, the sublinear regime $\sigma\in(1,2)$, where the Kirchhoff energy dominates the reaction term, remains essentially unexplored.

Positive solutions for parametric nonlinear periodic problems with competing nonlinearities
Electronic Journal of Differential Equations, 2015 We consider a nonlinear periodic problem driven by a nonhomogeneous differential operator plus an indefinite potential and a reaction having the competing effects of concave and convex terms.

Positive solutions for nonlinear Robin problems
Electronic Journal of Differential Equations, 2017 We consider a parametric Robin problem driven by the p-Laplacian with an indefinite potential and with a superlinear reaction term which does not satisfy the Ambrosetti-Rabinowitz condition. We look for positive solutions.

On p-superlinear equations with a nonhomogeneous differential operator
We consider a nonlinear elliptic equation driven by a nonhomogeneous differential operator and with a (p−1)-superlinear Carath´eodory reaction. Our formulation incorporates as a special case equations monitored by the p-Laplacian.

Superlinear Neumann problems with the p-Laplacian plus an indefinite potential
, 2017 We consider nonlinear Neumann problems driven by the p-Laplacian plus an indefinite potential and with a superlinear reaction which need not satisfy the Ambrosetti–Rabinowitz condition.
