Kramers rate for Brownian particles in excitable media with deformable double-well substrates
Alain M. Dikande
We address the Kramers escape problem for Brownian particles in bistable substrates with deformable double-well shapes. The shape deformability is considered of three distinct form…

Manning-type potential induced by kink scatterings with phonons in molecular chains with hyperbolic double-well substrates
Alain M. Dikande
A rescaled Manning potential is obtained in the analysis of scatterings of small- amplitude excitations with a kink defect. The generic model is a nonlinear Klein- Gordon Hamiltoni…

Leapfrogging of a deterministic model for microeconomic systems in competitive markets
Alain M. Dikande, H. Ntahombagana Matabaro
The Behrens-Feichtinger model provides a deterministic picture for the co-evolution of sales of two firms, producing the same goods and competing in a common market. The model invo…
