Omar Al-Raisi, Mohammad Shahryari
We introduce a unified method for study of 2-dimensional invariant subspaces of matrices and their corresponding super-eigenvalues. As a novel application to non-commutative algebr…

On -transitive groups and conjugate separable -subgroups
Omar Al-Raisi, Mohammad Shahryari
For a given variety of groups $\X$, we develop a systematic theory of $\CSX$-groups and $\XT$-groups, extending ideas proposed in \cite{Shah}. We analyze the interplay between thes…
