We consider a steady-state heat conduction problem P for the Poisson equation with mixed boundary conditions in a bounded multidimensional domain Ω. We also consider a family of problems Pα for the same Poisson equation ...

We consider a bounded domain nR⊂Ω whose regular boundary 21ΓΓ=Ω∂=Γ∪ consists of the union of two disjoint portions 1Γ and 2Γ with positive measures. The convergence of a family of continuous Neumann boundary mixed elliptic ...

We present a self-consistent model for the tidal evolution of circumbinary planets that is easily extensible to any other three-body problem. Based on the weak-friction model, we derive expressions of the resulting forces ...

Polaskia chende is a columnar cactus endemic to central Mexico, where it is managed via silviculture due to its edible fruits. We aimed to analyse the consequences of management on population genetics and compared information ...
