This diffusion-type equation exhibits numerous noteworthy properties. One such property is the conservation of mass, momentum and energy. The numerical methods in this thesis, namely the local and recovery discontinuous Galerkin methods for diffusion-type equations, maintain this over large and truncated domains. Employing these methods results in stability results that fall in line with theoretical expectations. However, the findings also include unexpected convergence and asymptotic behaviors, which prompt further investigation.application/pdfen-USCC BYConservationKinetic Fokker-Planck equationLocal discontinuous GalerkinRecovery discontinuous GalerkinApplied mathematicsPlasma physicsApplied mathematicsThesis
