Structure-preserving discretization techniques preserve fundamental structure of operators and operands found in partial differential equations. Classical discretization techniques sometimes neglect these structures, and as a result, fail to simulate the desired physica behavior. In this thesis the existing structure-preserving framework for elliptic partial differential equations is applied to isogeometric analysis. De Rham conforming B-splines are derived that conserve the topological structure of the derivative operator in the discrete setting. This framework is expanded to be able to discretize hyperbolic partial differential equations, which is applied to derive an energy-preserving discretization for the incompressible Euler equations.
