Three nontrivial solutions for nonlinear fractional Laplacian equations

open access: yesAdvances in Nonlinear Analysis, 2018
We study a Dirichlet-type boundary value problem for a pseudodifferential equation driven by the fractional Laplacian, proving the existence of three non-zero solutions.

Distributed theorem proving by Peers [PDF]

open access: yes, 1994
Peers is a prototype for parallel theorem proving in a distributed environment. It implements a number of strategies for refutational, contraction-based theorem proving in equational theories, whose signatures may include associative-commutative (AC ...

“It Is Much Safer to Be Sparse than Connected”: Safe Control of Robotic Swarm Density Dynamics with PDE Optimization with State Constraints

open access: yesAdvanced Intelligent Systems, EarlyView.
This paper proposes a novel control framework to ensure safety of a robotic swarm. A feedback optimization controller is capable of driving the swarm toward a target density while keeping risk‐zone exposure below a safety threshold. Theory and experiments show how safety is more effectively achieved for sparsely connected swarms.

Strong sequences and partition relations

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2017
The first result in partition relations topic belongs to Ramsey (1930). Since that this topic has been still explored. Probably the most famous partition theorem is Erdős-Rado theorem (1956).

Formal verification of physical human-robot interaction using interactive theorem proving

open access: yesJournal of Intelligent Systems
Physical Human-robot Interaction (pHRI) involves physical collaboration between humans and robots to perform tasks safely and efficiently in shared environments. Traditionally, pHRI behavior has been analyzed using analytical or simulation-based methods,

How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

open access: yesAdvanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

On a new generalized symmetric vector equilibrium problem

open access: yesJournal of Inequalities and Applications, 2017
In this paper, a new form of the symmetric vector equilibrium problem is introduced and, by mixing properties of the nonlinear scalarization mapping and the maximal element lemma, an existence theorem for it is established.
