Fully non-zero matrices and generators of full algebras of operators
Laurent W. Marcoux, Heydar Radjavi, Bamdad R. Yahaghi +1
In a wide variety of fields, every non-scalar matrix is similar to a matrix all of whose entries are non-zero. We give extensions of this result, including some in the division…

Spectrum in alternative topological algebras and a new look at old theorems
Bamdad R. Yahaghi
In this paper, we consider real and complex algebras as well as algebras over general fields. In Section 2, we revisit and prove several results on (quadratic) algebras over genera…
