All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
We characterized the group of linear operators that strongly preserve r-potent matrices over the binary Boolean semiring, nonbinary Boolean semirings, and zero-divisor free antinegative semirings. We extended these results to show that linear operators that strongly preserve r-potent matrices are equivalent to those linear operators that strongly preserve the matrix polynomial equation p(X) = X. where p(X) = Xr1 + Xr2 + ... + Xrt and r1>r2>...>rt≥2.
In addition, we characterized the group of linear operators that strongly preserve r-cyclic matrices over the same semirings. We …
