Matrix approximations of operators
B. G. Giraud, S. Karataglidis, K. Murulane +1
The approximate representation of operators by finite matrices is analysed in terms of accuracy and convergence. The identity operator, for example, can be reconstructed using a ba…

Concavity Theorems for Energy Surfaces
B. G. Giraud, S. Karataglidis
Concavity properties prevent the existence of significant landscapes in energy surfaces obtained by strict constrained energy minimizations. The inherent contradiction is due to fl…
