Optimal error estimates for a discontinuous Galerkin method on curved boundaries with polygonal meshes
Adérito Araújo, Milene Santos
We consider a discontinuous Galerkin method for the numerical solution of boundary value problems in two-dimensional domains with curved boundaries. A key challenge in this setting…

Jacobi Hamiltonian Integrators
Adérito Araújo, Gonçalo Inocêncio Oliveira, João Nuno Mestre
We develop a method of constructing structure-preserving integrators for Hamiltonian systems in Jacobi manifolds. Hamiltonian mechanics, rooted in symplectic and Poisson geometry,…

Jacobi Hamiltonian Integrators: construction and applications
Adérito Araújo, Gonçalo Inocêncio Oliveira, João Nuno Mestre
We propose a systematic framework for constructing geometric integrators for Hamiltonian systems on Jacobi manifolds. By combining Poissonization of Jacobi structures with homogene…
