Frame Representations and Parseval Duals with Applications to Gabor Frames
Let {xn} be a frame for a Hilbert space H. We investigate the conditions under which there exists a dual frame for {xn} which is also a Parseval (or tight) frame. We show that the existence of a Parseval dual is equivalent to the problem whether {xn} can be dilated to an orthonormal basis (under an oblique projection). A necessary and sufficient condition for the existence of Parseval duals is ...
متن کاملHigher Weights of Affine Grassmann Codes and Their Duals
We consider the question of determining the higher weights or the generalized Hamming weights of affine Grassmann codes and their duals. Several initial as well as terminal higher weights of affine Grassmann codes of an arbitrary level are determined explicitly. In the case of duals of these codes, we give a formula for many initial as well as terminal higher weights. As a special case, we obta...
متن کاملOn Higher-order Linear Port-Hamiltonian Systems and Their Duals ?
We formulate a behavioral approach to higher-order linear port-Hamiltonian systems. We formalize constitutive laws such as power conservation, storage and (anti)dissipative relations, and we study several properties of such systems. We also define the dual of a given port-Hamiltonian behavior.
متن کاملHigher Dimensional Representations of Graphs
Graphs are often used to model complex systems and to visualize relationships , and this often involves drawing a graph in the plane. For this, a variety of algorithms and mathematical tools have been used with varying success. We demonstrate why it is often more natural and more meaningful to view higher dimensional representations of graphs. We present some of the theory and problems associat...
متن کاملToward Higher-Order Qualitative Representations
Qualitative reasoning typically proceeds by instantiating type-level constraints to produce a complete propositional model of a scenario, and then reasoning over this propositional representation. As we pursue the problem of learning qualitative models and applying them to openended construction domains, the limitations of this approach have become increasingly acute. Consequently, we have been...
