In the realm of applied mathematics, this Ph.D. proposal is related to the numerical solution of partial differential equations through the discretization of the associated dependent variables. In the frame of finite element analysis, it is focused on the construction of high-order schemes on polygonal meshes. The industrial application of such developments is the solution to the Boltzmann equation that describes the transport of neutrons within the core of a nuclear reactor. In this context, many modern codes use a finite-element-based discretization (more precisely, an upwind discontinuous Galerkin scheme) on triangular or quadrilateral meshes spanning the spatial domain. This efficient and versatile method is well suited for the developm...
