We study existence of principal eigenvalues of a fully nonlinear integro-differential elliptic equations with a drift term via the Krein-Rutman theorem and regularity estimates up to boundary of viscosity solutions. We ...

We consider a model of diffusion in random media with a two-way coupling (i.e., a model in which the randomness of the medium influences the diffusing particles and where the diffusing particles change the medium). In this ...

The classification is an important step in the extraction of geometric primitives from LiDAR data. Normally, it is applied for the identification of points sampled on geometric primitives of interest. In the literature ...

In this work the differentiability of the principal eigenvalue lambda = lambda(1)(Gamma) to the localized Steklov problem -Delta u + qu = 0 in Omega, partial derivative u/partial derivative nu = lambda chi(Gamma)(x)u on ...

In this paper we give sufficient conditions for the existence of a positive principal eigenvalue for a periodic parabolic Steklov problem with a measurable and essentially bounded weigth function. For this principal ...
