A necessary and sufficient condition for a dual matrix to have a {1}-dual generalized inverse is obtained. It is shown that a dual matrix always has a {1}-, {1,3}-, {1,4}-, {1,2,3}-, {1,2,4}-dual generalized inverse if and only if it has a {1}-dual generalized ...

Let [a]∈Zn be invertible. Prove that [a].[x]=[a].[y]⇔[x]=[y]. Is this true when there is no assumption that [a] is invertible? Inverse of a Matrix: In this case, the matrix must be a square matrix. The ...
Regardless of density, the inverse slope of the leading straight-line incompressible valley that extends to the zero-field limit67 provides the Chern number. As a probe, this field does not alter our claim of a QSH phase at zero field. In the non-interacting case (Fig. 1a) at β =...

scenario where we have numerous covariates, but not all are necessarily related to the outcome. Therefore, this simulation study also helps to demonstrate whether including some redundant information makes a covariate-adjusted method perform worse, or if it still performs no worse than the ANOVA ...
