A 2D climate energy balance model coupled with a 3D deep ocean model.
We study the method of layer potentials for manifolds with boundary and cylindrical ends. The fact that the boundary is non-compact prevents us from using the standard characterization of Fredholm or compact pseudo-differential operators between Sobolev spaces, as, for example, in the works of Fabes-Jodeit-Lewis and Kral-Wedland . We first study the layer potentials depending on a parameter on compact manifolds. This then yields the invertibility of the relevant boundary integral operators in the...
The role of the second critical exponent , the Sobolev critical exponent in one dimension less, is investigated for the classical Lane–Emden–Fowler problem , under zero Dirichlet boundary conditions, in a domain in with bounded, smooth boundary. Given , a geodesic of the boundary with negative inner normal curvature we find that for , there exists a solution such that converges weakly to a Dirac measure on as , provided that is nondegenerate in the sense of second variations of...
Cotangent type functions in Rn are used to construct Cauchy kernels and Green kernels on the conformally flat manifolds Rn/Zk where 1 < = k ≤ M. Basic properties of these kernels are discussed including introducing a Cauchy formula, Green's formula, Cauchy transform, Poisson kernel, Szegö kernel and Bergman kernel for certain types of domains. Singular Cauchy integrals are also introduced as are associated Plemelj projection operators. These in turn are used to study Hardy spaces in this...
