Mixed Isogeometric Methods for Hodge–Laplace Problems induced by Second-Order Hilbert Complexes [PDF]

Partial differential equations (PDEs) play a crucial role in mathematics and physics to describe numerous physical processes. In numerical computations within the scope of PDE problems, the transition from classical to weak solutions is often meaningful.
